OK - I have hacked an implementation of 1 into opengk. All in all it
took me 45 minutes (someone who know pwlib could have done it quicker!)
Apply the patch below, run
opengk -x -l log.txt
and point galeon at http://hostname:1719/who
You will see a page with links to the users who are registered.
This took me next to no time to implement - I think extending a
gatekeeper is a much better solution than using ils.
