But I reckon USB is going to be tricky, you'd need to connect via a midi which gets split as it leaves the device...but you haven't got midi inputs so this isn't really an option.
You'd have to split the usb out from the Mbox and connect to each MBP. I don't see it working.

These are probably connected via your Mbox, so that depends on whether your Mbox can connect to 2 MBP's simultaneously, which I doubt. I've never tried this, or read about anyone doing it, so I'm just taking a guess at these answers. I foresee much fiddling and frustration should you pursue this endeavor
