Hello. Thank you for all the feedback!
I am trying go slowly get put some more effort on this project, but I think it's time for a few early adopters/developers to join.
The plan is to meet on IRC a couple of times and asign a few tasks to make some progress.
If any of you is interested please let me know (preferably through the discussion group http://groups.google.com/group/jgf-users).
