(Sorry for the repost, didn't want this to get lost in a thread about naming conventions.)
For those of you insterested in playing with Pylons, I've hacked out spec files and built RPMs for F8:

I haven't done anything other than make sure that everything installs and paster can do "create" and "serve", so consider this early access.
I believe all the other prereqs (like python-simplejson and python-nose) are available via yum. Feedback welcome! If these test out ok for you all, I may submit them for F9.
