They have a brief sales video, I've embedded here. They offer a free trial but I believe you'd need to already have the Leica Disto in hand to take advantage of it. The software boils down to these concepts: Defining Levels and Lease holders and then using 5 different tools to deal with measurements: Distance, Ortho, Offset, Rectangle and Triangle. They claim that with these features you will be able to create any drawing, shape and size of buildings.
I think attempting to evaluate this type of technology would benefit from a few videos that show it in use, the practical application of it on-site. Too bad we didn't get this for Glorius Gadgets at RTC in Stone Mountain! Maybe at RTCEUR 2013 in Delft, Holland...it's pretty close by for them!
