It's a Linux system, so network programming is totally possible. You'll have to do some of the heavy lifting yourself or port one of the many, many libraries out there to it.
I am not aware of any plans for ROBOTC to support network programming, but that's not to say that it won't happen. It will support Bluetooth and all that stuff, of course.
