Sounds like you might want to look into Condor [1]. There is an ebuild request [2], but nobody has written an ebuild yet. The difference between Gentoo and other distributions would primarily be in package management, which would be unrelated to Condor since we don't package it yet. You would probably set up a single build server and run emerge with the '--buildpkg' or '--buildpkgonly' flag, then set PORTAGE_BINHOST (see make.conf.example) on the other machines to retrieve binary packages from the build server. There are a number of tools to make it easier to run commands on clusters and keep them in sync, such as clusterssh, pdsh [3], pssh, c3, csync2, cfengine, rsync and others.
