Tunneling SSH Through Screensharing in OS X

I overhead an exchange between two friends that I thought was interesting. One needed help from the other and asked him to SSH into a machine. The place where the second friend works blocks outgoing port 22, the port SSH lives on. Don't ask me why. The solution? Friend one does a screenshare to friend two who uses the shared machine to SSH. First time I've seen screensharing being used to tunnel SSH.
