I found this site describing directions to get wine running on ppc. I haven't tried this myself but according to the site should be able to emulate an x86 processor and then run wine on a ppc. The link gives directions and links to the packages you need to accomplish this. Has anyone heard anything about this working, or even better is someone willing to try. I just thought i would share this with the community.
and here is the link:
wine for PPC OSX (don't know, maybe that would help, prbly not though)
