I don't see why not -- although we could just "fault them in" lazily as-needed.

I don't really understand the question. I was assuming the workflow would be:
* George something on github.com/gwd/sig-virt-xen
* George sends pull request to github.com/CentOS/sig-virt-xen
(possibly cc'ing centos-virt mailing list)
* Opportunity for discussion, review, objections, suggestions, &c
* Eventually it gets pulled into CentOS/sig-virt-xen
* ...then pulled into git.centos.org for testing.
Did you mean something else?

Well each SIG can come up with a method of managing patches that works
for them; but feel free to suggest this to people. :-)
