Well, in that case, I have a VM server that I'm willing to leverage for
a few Fedora and/or CentOS slaves if you can use them.  I'm happy to
host and administer the slaves.  (Beyond just a few slaves might tax the
hardware too much, affecting the other VMs; the host is currently
memory-bound and extending the RAM is way expensive because it requires
8 sticks of DDR2).
