I've just been a bit worried I suppose, because there still hasn't been 
an official announcement of complete (or at least near-complete) support 
for Fedora 11 or 12 on the Planet website yet. I've installed Planet 
CCRMA on Fedora 11 machine, but alas don't seem to ever get around to 
trying it out.

I was interested in trying to see if I could get Planet CCRMA RPMS to 
build on a ppc-based Power Mac running Fedora with just making the 
appropriate changes to config files and spec files of your existing 
SRPMs to adjust for the architecture. Do you think that might work? If 
not, the only programming languages that I ever learned to use were 
BASIC and FORTRAN, which I am sure doesn't help the Planet followers 
much. However, I would like to try see if the build can be done just by 
changing configs and specs.

Gee, I thought you used to detest the idea of moving packages over to 
the f.k.a. "Fedora Extras." What's changed?

I think I had tried rebuilding Planet real-time kernels for 9 and 10 
back when I had those installed, and neither would work. There was 
always a compile-time error. I think I even tried rebuilding without 
changing the config file nor the spec file, and I couldn't get the 
PLanet rt kernel to build. Also, it looked as if the config files I made 
for those kernels get overwritten or bypassed in the spec file such that 
a default config file is used anyway, although I'm not entirely certain 
of that. I might be wrong, but it looks like the same bypass/overwriting 
is happening when I try to rebuild a custom kernel based on the standard 
non-rt Fedora kernels on Fedora 12.
