I guess that means we should get in touch with them to get on the 
supported systems list. =)

The OSL (Open Source Lab), which hosts much of the Gentoo infrastructure 
and runs a lot of other projects on Gentoo boxes, takes a similar 
approach to what I mentioned above. I think you already know Corey 
Shields, so you could ask him about it.

You may also want to take a look at 
http://article.gmane.org/gmane.linux.gentoo.devel/43984 -- it's from one 
of our developers who's deployed fairly decent-sized clusters.

Thanks,
Donnie
