[sldev] Question: Replacing current group chat with XMPP?

[Dahlia Trimble]

Please forgive the brevity of my prior response. Ryan is correct, Opensim
provides a separate site where code under the GPL or other licenses that are
meant to work with Opensim may be hosted if they are not chosen to be
included in the core svn. If an instant messaging protocol extension could
be made to work with Opensim, than that may be a good place to host it. If
there were changes needed to the Opensim core in order to accomidate these
extensions, then they would need to be submitted as patches and must be made
available under the conditions outlined in the Contribution Policy available
at: http://opensimulator.org/wiki/Contributions_Policy
I'm with Rob on this discussion now, if it's pertaining to opensim then it
should move off of this list and to the opensim-dev list:
https://lists.berlios.de/mailman/listinfo/opensim-dev

Note that GPL zealotry is *not* the goal of Opensim devs and will most
likely be frowned upon in the opensim-dev list.
