I read:
ask this question, but.. if I want to run PD on linux, and I have a mac osx, is linux compatible/installable on the mac
yes - for some odd reason I'd recommend debian http://www.us.debian.org/releases/stable/powerpc/
and what would be the implications of that
hmmm you would have linux on mac hardware ;)
(could it coexist with osx, etc? I have panther...
absolutely - and as carmen pointed out - apart from dual-booting you can even run one os in a virtual machine (like mol -> http://maconlinux.org/) within the other.
to install however you'll need to repartition your hd (or use a 2nd drive) to do this non-destructively you'll need some tool that won't come with your debian install image. (like hmmm what's the name again iPartition ?)
