jbm, your points are valid, and I agree, it's a good idea, however, I still think, wouldn't it be nice, if you found out that although you can't afford another machine, you can afford MIR, and with some work arounds, like printing your tracks and not running the mix live (providing software can work that way) - you could use your existing (future tense - 8cpu mac pro) not only for sequencing but, albeit at a compromise, also for MIR, and not buy the extra hardware - it would be good to have that choice.
