Yup, this one works well for a long time especially if you
have at least 128Kbps links and moderate sized repository
modules. The bigger the network pipe or the smaller the
module to be handled, the easier it is to use a WAN. If you
are using compression over the WAN link, you will probably
have better performance (this presumes you are not dealing
with compressed binary objects in your repository) than an
uncompressed link (c.f, 'cvs -z6').

This can work if you follow the *BSD model of CVSup mirror
repositories and use CVS_LOCAL_BRANCH_NUM for truely local
branches and then point your commit to the master repository
for the 'public' branches.

Google finds a few that look to be potentially useful to you:

 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvsup.html
 http://www.scriptkiddie.org/freebsd/setting_up_local_repo.html
 http://www.cs.wustl.edu/~nanbor/CVSUP/cvs-repo-sync.html

I am sure you could find more now that you know where to look.
