[Opensim-dev] User services refactoring status

Wed Jan 6 15:41:23 UTC 2010

I am working on it and it's about to be launched (due to the framework I
use, Code Igniter, possibly with a MIT or Apache license, but open source).

A soon as I clean the code will be available for public download. It was
stable on October but then... Modern Warfare 2 was launched and I love AK-47
:-)

I called it unga :-) http://ai-designstudio.net/en/blog/1008

I am planning to make a Python unga using Tornado/Twister frameworks, but I
haven't time enough...

Greetings
