Suppose I want to use my powerbook for tracking, but edit on my desktop ... and suppose I buy an Mbox ... can I put the PT-LE software on both computers? I'm guessing I would have to move the Mbox back and forth between machines to authenticate the software on the machine I'm currently using -- would that actually work? Also, suppose I hang the Mbox off the USB port of my desktop. Would I then be able to use the Delta 1010 card installed on that machine for output (or even input/output), or would I be restricted to using the Mbox as I/O? thanks, david David F.
