Streaming Revit!?

Autodesk Labs has come out with something new and interesting. The ability to test drive and stream apps from their servers:

Project Twitch

This is really interesting to me, as it means that potentially we could do something very similiar internally, or, eventually, like many "cloud computing" applications, we need only pay for how much access we require to applications like Revit, Maya, Autocad, and our IT deptartment does not have to worry about maintaing the high powered comptuers or software.

Now, I realize that likely in the short to medium term server side apps will not replace the functionality of having something like Revit or Maya local on your computer, however, with a decreasing need for 2D Autocad, I could see high value in being able to "buy direct" from Autodesk, how much, and when we need access.
