Thanks Justin, I am only developing the Kinect plugin, the project is for
the very cool folks in http://missionv.ie/ who have an OpenSim project with
primary schools in Ireland.

Thanks for that link. The fact that I connected twice and saw myself logged
out of the first connection could be down to the server configuration or
the way I connected perhaps?

I have developed a working Kinect controller region module. My
understanding from your comment is that I could place the dll on the server
and it act as a mini-server (inside the OpenSim server) taking HTTP
requests and running them directly against a specified avatar. The OpenSim
server wouldn't kick the first logged in avatar because no actual 'logging
in' would take place a second time. I would presumably have to build
in authentication as otherwise it would be a potential security hole.

Thanks, I found the region module wiki documentation could have had more
examples, but it was great to have what was there.

Interesting, I'll investigate that too.

Thanks for the reply and the links.
