There is a cycle stand and a PC software to training indoor that uses videos (and internet to race friends) in that software you can bicycle recorded tracks, someone more into bike-racing probably know what I mean (sorry I don't remember the name). I think it would be nice if you could create data the same format they use its probably just a video with embeded GPS data...
I have got a virtual trainer, it can load GPS files and you can drive, alone or on Internet, the tracks with Google Earth 3D.
The video's are a different matter, they only work correct with Tacx video's. This because the height data and brake force are embedded.
I am a tester for them, they not intending to make it open for other video's.
GS team I wish you a good result at the exhibition.
