So, lets get on with what's happened since:
On June 30th, OSX 10.4 was announced.
On July 3rd, co-creator Stefan Weyergraf was hit by a train and killed. Condolences to his family and friends.
On July 4th, someone got 10.4 running on PearPC.
On July 17th, OpenDarwin 7.2.1 was released.
And just within the last couple days, direct access to physical CDROM drives was added, and surprisingly enough Altivec support was added to PearPC giving us G4 processor emulation.
Also during the last month, Cybermagellan at Emaculation opened an archive of official builds and nightly CVS builds; available here. Altivec builds can be found there as well.
For a while there some of the new CVS builds that were coming out were extremely buggy, though things were fixed quickly enough—even if it didn't feel like it happened quickly. Things seem to be running smoothly enough now.
