(...) It seems to me that, given the current hardware, the choices are: send junk or let the tower go dead. My thinking is that if you send junk and trample something, so be it; the tower would have gone dead anyways, forcing you to lose whatever it (...)

It appears Roblab 2.0 would also be an alternative for your project. Robolab has two different direct modes to control the RCX, one of which is using a remote connection like the Internet.
