FCP & Avid on the same system update

Hi all,before going into the subject just want to let you know that i did my search on this forum but the last posts date from the beginning of this year so i'm trying to find out if there's new developments on this: i'm looking to build an editing system at home, most of the work i'll be doing is offline so i need to be "compatible" with both fcp and avid to taste. I guess by now you got the idea.....i want to install both applications on a:
Mac Pro Two 8 Cores 2.8GHz Quad-Core Intel Xeon “Harpertown” processors
4GB memory (800MHz DDR2 fully-buffered DIMM ECC)
ATI Radeon HD 2600 XT graphics with 256MB memory
320GB Serial ATA 3Gb/s 7200-rpm hard drive1

Like i said i read some posts where people mention issues with leopard, installing apps in two different drives or on 2 partitions on the same drive etc, i know that my question seems to be simple but it really isn't: is it possible for the 2 apps to co-exist on the same system and for me to edit and hand out offline projects to people working on both fpc and avid? Any help on the subject will be really appreciated.
Adrian.
