Mod_groups-like disco functionality?

Back in the day, jabberd 1.4 had a mod_groups roster plugin that allowed users to browse/discover and register to groups. I would find that very useful - even the the ability to setup groups that may be registered to instead of assigned at the admin console.

Is this something others would find useful, is there functionality like this in JM I’'m missing?

I’‘ll add it as a feature request if I’'m not alone in this…
