With respect to the ssh logins required for each cvs operation, I tend
to use opportunistic connection multiplexing.  e.g., in my
~/.ssh/config I have:

----
ControlMaster auto
ControlPath   ~/.ssh/sockets/%h_%p_%r_multi.sock

Host cvs.fedora.redhat.com
    Compression      yes
    CompressionLevel 3
----

And then I just do a "ssh -f -N cvs.fedora.redhat.com".  It
authenticates me once, then just kicks around in the background until
I perform a network operation though CVS, at which point the "new"
connection is routed through the existing one.  If I haven't forked
off a connection to c.f.r.c, no biggie, ssh just connects per usual.

This won't help with selectively pulling down CVS, but it should make
each operation a smidge faster :-)
