Here are a couple of resources:
I just did a google search. I have never actually used remote desktop with 3D mouse.
My guess is that it is going to choppy and spotty.
I have used my 3D mouse with my computer connected to a tv display in a conference room (not direct connection, but through the network). When I tried to actually LOOK at the TV and use the 3D mouse at the same time, it drove me bonkers because I was used to the instant gratification from my computer at my desk. I ended up having to set up a direct connected monitor to look at because I couldn't stand the delay between what I was doing and the TV.
Thanks for the info. We have tried a couple of those programs out but nothing seems to work. We would love to have people working on SolidWorks over remote desktop and this is the last hurdle. I will update this post if we have any success.
