Merging Projects From Different Computers/sequence, Mac & PC Options

[Atahualpa]

Hi,
I am collaborating with a friend on an electronic music project, now, he works on a PC and Cubase, I work on DP4.52 and Mac. If we decided to use only one computer on a live performance (to have a unique internal clock), could we keep separated audio track versions of his and my tunes so that we could mix them in real time (mixing within each tune and against eachother for continuity)? In this case what kind of platform would be use to montage his and my material (which I guess would be an array of audio tracks)? The other only possiblility I see is creating MP3s of his and my stuff, but in this case we would have a much smaller maneouver margin, since we could mix the tunes against eachother using a virtual mixer like Traktor DJ, but we could not manipulate induividual tracks within each tune during the gig.

I hope my above description is clear enough and hopefully some of you have already experience on this topic.

Thanx in advance and groove on!!!

Thanks a lot Lepetitmartien!

Is there a way to try out Abbleton (demo version)? Because I think the software is pretty expensive...

Sorry for having posted twice my question, but it seemed the first time I lost connection and it did not post it immediately.
