Thats not so easy. What about this:

cvsup		IN CNAME	cvsup1.freebsd.org.
cvsup		IN CNAME	cvsup2.freebsd.org.
cvsup		IN CNAME	cvsup3.freebsd.org.
cvsup		IN CNAME	cvsup4.freebsd.org.
cvsup		IN CNAME	cvsup5.freebsd.org.
cvsup		IN CNAME	cvsup6.freebsd.org.
cvsup		IN CNAME	cvsup7.freebsd.org.
cvsup		IN CNAME	cvsup8.freebsd.org.

If you simply put "cvsup.freebsd.org" into your supfile you'll get
randomly one of them. This should spread the load fairly well. If
you want a special one then simply put "cvsupX.freebsd.org" into
you supfile.

Aint that easy?

I don't see any appearant reson (short of network connectivity) that
one *needs* to get always the *same* server.
