The point here is not to find some arbitrary way of tunneling CVS traffic
over SSH, but to be compatible with the way, eg, sourceforge's CVS over
SSH works.  I don't know the details, but it's whatever the CVS
client does when you give it -d:ext:user at host:/path as the cvs root, and
when CVS_RSH is set to "ssh".  My assumption is that this is, as you say,
launching a remote cvs client and communicating over stdio, but what this
communucation looks like I have no idea.  I'm pretty sure it's not the
same as the pserver protocol.

Anyone better informed, or should I look it up?  Julian?
