Sharing a working directory among multiple developers is possible, but
not advisable.

I am unable to reproduce your problem on a Redhat 7.3 GNU/Linux system
with a cvs-1.11.6, the remote server is running FreeBSD 4.8-RELEASE in
this particular case.

  % ssh server umask
  0022
  % umask 002
  % umask
  0002
  % export CVSROOT=server:/tmp/testit

If this the problem you are reporting, then show us the commands
that you use to reproduce the problem.

What cvs does with the ,v file permissions is not relevant to what is
used on checkout.

Yes.

I do not see how this is relevant to your bug report.
