I've been playing with Software Collections (SCL) at work. When I'm a little 
further along, I'll be happy to share my knowledge with the group either on 
the list or as a presentation. Basically, software collections allow you to 
install a whole other set of RPMs on a Fedora/RHEL/CentOS system even if they 
might ordinarily conflict with  packages that come installed by default on the 
system. It's a great way to, say, install Perl 5.14 and related CPAN modules 
on a CentOS 6 system that only has Perl 5.10 by default.
