I'm sorry, I didn't read this message before my reply.  I see you've already
covered everything in my reply, so you can ignore it.

If stunnel doesn't work, how about this idea: what if you hand out an
unencrypted SSH "private" key to all users, and put in a .ssh/authorized_keys
on the server with a forced command that restricts what the users can do
to specific rsync commands?  That will still encrypt the connection, and
even though the authentication key will be well-known it should be safe
because the authentication key is independent of the encryption key.
