When I need to do something like this, I typically have the commitinfo
run a script to do something like this:

ALL $CVSROOT/CVSROOT/commitcheck

where $CVSROOT/CVSROOT/commitcheck looks something like this:

                   ------- start commitcheck -------
#!/bin/sh

case "`/bin/hostname | /usr/bin/tr A-Z a-z`" in
mycvsmaster.mydomain.com)
        : # OK
        ;;
*)
        echo "Please commit on mycvsmaster...."
        exit 1
esac

if $CVSROOT/CVSROOT/cvs_acls ${1+"$@"}
then
        : # ok
else
        echo "Access control checks failed! (cvs_acls) 1>&2
        exit 1
fi

if $CVSROOT/CVSROOT/commit_prep ${1+"$@"}
then
        : # OK
else
        echo "commit_prep failed!" 1>&2
        exit 1
fi

exit 0          # Lets do it!
                    ------- end commitcheck -------

So, even if someone mirrors the repository, they will not be able to
commit to the mirror unless their hostname happens to believe itself
to be the mycvsmaster host. I also do not trust that their PATH will
contain a hostname that does not lie by using the full pathnames to
the commands I need.

Note that similar logic may need to be applied for tags, but I figure
that I don't care if a user is messing with local tags in a mirror. I
only want to make sure they do not lose any commits.

        Enjoy!
