WiFi nor USB will ever do the hard real-time unless you have the controller to cache the movements (Like Li's FPGA-USB controller does). That being said, there should be no reason why you cannot have a GUI that controls things remotely. Take a look at miniemc which uses a web browser. I am not sure of the protocols they use, but it is something to take a look at. Also, there are people that were playing with devices over the Net.
I do not know the status of the RT protocols on a Beagleboard. You can look at the various RT kernels (Xen, RTAI, RT-Preempt) and see if any of them will work for you on the BB.
