Check out this URL:

http://www.brandonhutchinson.com/ssh_tunnelling.html

you could probably combine that with key auth instead of passwords. 

And instead of having them always trying to ssh in, you could setup a
file on a webserver and have them parse the file. if they see their
hostname in the file it means they should "call home". just have em
check that file every 5 minutes or so.
