There isn't an easy button to just eliminate shared coordinates in a project. You can move the Survey Point back to the same spot as the Project Base Point and then use Specify Coordinates at Point to reset the coordinates the file is using. Sounds like I just countered my first statement?
I'm referring to the relationship between files when you use Acquire Coordinates or Publish Coordinates. Once two files are sharing coordinates you can't really remove this relationship. If you remove the link and import it again (Auto - Origin to Origin) the relationship survives. For example you can try to Acquire Coordinates from the file again to "reset" them and Revit will say that it is already sharing coordinates with the file.
To remove (really more like replace) the relationship I use a new (empty) file that is based on the stock Revit template default.rte. I import this file and Acquire Coordinates from it instead. Revit can only acquire coordinates from one source file so using a different file resets it to match this new file. Now it is possible to acquire them from the original file after removing the C/M relationship.

Steve, which version are you using? Autodesk "fixed" one source aquisition and the solution you descibe stopped working in the 2012 version.
I'm certain I've been able to do this with 2012, not sure I've tested it in 2013. I see no reason why it shouldn't continue to work. The Acquire Coordinates tool doesn't discriminate against a file unless it is already sharing coordinates with it.
Mostly related:
You'd think it would be useful to be able to compare the Survey Point in a Link to the Survey Point in the parent model, no?
That would be very useful if you're trying to line up a Link hat has gone astray. Sounds simple: Turn on both Survey Points, and move the Link from one to the other.
But no!
You can't turn on the Visibility of either Survey or Project Base Point in a Link.
I've been asking for that ever since they exposed the Survey Point, but it hasn't happened yet.
Not sure whether this is new in 2013, but when you move a link that you acquired coordinates from, when saving the host file (if you did not previously save the shared coordinates back to the link), Revit prompts you to save the updated shared coordinates to it, or not save, or disable shared positioning. The latter should do the trick, although it seems that you have to save, exit and re-open the host project in order for the link to properly report the parameter "Shared Site" as after doing so.
I have an easy way to remove the shared coordinates... Open file "detach from central" next "Detach and discard worksets" then save the project as a template, next go to "R" and new file from template, select the template you just created from the project, then save as with project name... All links are still linked but the shared coordinates are now gone. You lose the worksets and will have to recreate them (give and take), but this is how I manage to remove shared coordinates and it works

To remove shared coordinates, open file "detach from central" "detach and dicard worksets" save file as a template, open an new file using this template created from the project then save the file back as the project, all links remain but the shared coordinate is removed, you also loose the workset, not the element assigned to the workset. So it is give and take. But shared coordinates can be removed this way.

Great idea Steve! I can suggest to users who wish to reset their file-to-file relationship (because of the shared coordinates) but still to be able to maintain the same coordinates system, you can create a blank file from the same template and assign the same coordinate system values (as the existing models) at the SCaP . Save the blank model. Now it's time to open one of the established models, link in the blank model and acquire coordinates from the blank model. ONE IMPORTANT NOTE: YOU NEED TO MAKE SURE TO LINK IN THE BLANK MODEL VIA "ORIGIN TO ORIGIN" so that the origins fall in the same place. Now if you try to link in other models to this newly changed model via SHARED COORDINATES, Revit will say they are not sharing the same coordinates. To overcome this issue, you will need to make enough blank models to associate with each of the existing/established models. Basically just duplicating the blank model for X times! Once all of the individual models are associated with a blank model, you are now able to link revit models via shared coordinates to test out if they are sharing the same coordinates (be careful,we don' want to do that, it just for testing the method).
This method is only proposed when you have established shared coordinates and you want to replace this so that your revit models are not at risk of being messed up. Very convenient and efficient!
Recap: we just created a third-party model with the same coordinates values and associated each model to one of the blank models. As Steve said, each revit model is able to share coordinate with one source. We are just replacing the source via this method. Not having to move buildings, not messing with the graphics of the linked models, and replacing the file-to-file relationship due to the shared coordinate system are of the benefits of this method, I would say.
