If you have new boxes running the latest stuff that you want the latest
version of pkgsrc, you could keep it in /usr/pkgsrc-current and if you
have a couple of older boxes that are stable and shouldn't really be
touched (other than getting stuff out of pkgsrc), you could keep that
in /usr/pkgsrc-2005Q3 (should that be the branch you checked out).  You
could keep them on a central file-server and shared out via NFS, etc.

When you work with CVS, it keeps some state and meta info in CVS
subdirs, ie:

$ ls -l /usr/pkgsrc/www/apache

This last set of files is what CVS uses to determine what you've got in
comparison to what is in the CVS repository and send you just what you
need (what's been updated/changed) since the last update/checkout.
