On DST, do a rsync --daemon, and let it only listen to local host for
connections etc. in the rsyncd.conf
setup the tunnel(s) to DST:873 (The rsync port??) from base on like port
Then ssh to SRC, with port forwarding from SRC:5555 to base:4444 executing
"rsync sourcedir rsync://localhost:5555/destinationdir"
Anything else, you'll have to vi rsync.c and add it yourself ;^)
