I put up a little(*) server on to test this now. http://www.playsign.fi:28008/render Added camera controls to the web ui on Friday, and enhanced it today so that different users don't interfere others cameras. Is in naali develop. ~Toni (*) the server is a EeePC minilaptop, Atom processor, but nvidia gfx :p .. and hosted behind a 4MB dsl up here in the outbacks so may be a bit slow. We did test running headless with mesa software gl too for other reasons on Friday, would be helpful on the headless linux buildslave to run tests .. but that would allow normal hosting in some server space for this screenshot stuff.
