Yes, we do use cvs and copy build trees with rsync -a/cp -a.

The problem is that because our builds take that long, nobody does a 
global cvs update very often, but rather only on the parts he is working on.

It's user nightly that does an automated fresh checkout every night and 
sees if everything is fitting together and passes the tests. That makes 
it more attractive to copy the nightly build to continue your own work, 
because there is some guarantee that it builds, passes the tests and 
incorporated the stuff from the other teams.

Cheers,
