[Opensim-dev] Presenting unga: UGAIM grid servers with PHP

[Impalah Shenzhou]

Thanks for the advices Diva :-)

Actually I prefer to make unga compatible with robust implementation. From
my point of view robust is the standard into the opensim core and I am not
designing a new architecture for support servers... yet :-P

Cheers
