Well, I'm too dumb to speak for the technical side :) but the official software only allows 3 hubs at a time.
Well, WeDo is also compatible with a more open programming language called "Scratch" by MIT (download it for free at http://scratch.mit.edu/
), which is much more open and programmable as well as interactive compared to the WeDo software (still a drag-and-drop programming language). By using this, you could maybe have unlimited motors, but who honestly has enough USB slots for it to be practical? Also, unlike the WeDo software, on Scratch, you can't identify specific motors for certain commands - instead if you have say, 2 motors, by doing a command, it does the action for both of the motors. As well as that, the only other downside to Scratch for WeDo is that there's no block for "shaking" in the tilt sensor - but it really doesn't matter that much :P.
With Scratch, someone made these with WeDo:
Submarine project (uses WeDo to interact in-game): <iframe src="http://player.vimeo.com/video/6884185" width="400" height="250" frameborder="0"></iframe> (shows Scratch program too)
Balancing Robot (balances, but the trick is, it does it via the motion sensor!): <iframe src="http://player.vimeo.com/video/6669802" width="400" height="250" frameborder="0"></iframe>
Ferris Wheel (uses WeDo to interact in-game): <iframe src="http://player.vimeo.com/video/6969551" width="400" height="250" frameborder="0"></iframe>
So it does have some potential.
