The model of the wireless bridge would be helpfull... However:
I believe what you should start with is a simple forms GUI (classical), and Then I would need to know what you plan to use to "move" (user input actuator) i.e. mouse num pad remote etc...
the first thing that came to mind was to use the windows live PC controller, with XNA studio, and whatever messaging service you devise.. -(the added benifit of this is that you would have a "remote" and most of the dificult stuff is readilly available on the XNA forms not to mention all the versatility of the XBOX controller)
it seems to me that you intend to use ..?commands? like go forward go back.. (perhaps that is why you are looking at chat type "platforms".) however I believe it would be better to just use a "Internal Lab Frame" and use (1,0) for forward, (-1,0) backward etc..
and those data blocks would fall more into the "pure" networking-(of which I know very little) but I know enough to say it would probably be easier to work with then commands (especially when you want to progress to things like partial turning, and/or using an arm)
