Avatars in OpenSim
One of the problems with using SL is that one has to own/rent the land in which the environment is created and housed. While with OpenSim one only needs a web server which in a sense is highly appealing for creating permanent environments. Another problem we encountered when using SL was the time it took to execute our agent-based models due to the SL servers. So when I was shown by Chris Rouly this latest test on the ScienceSim Beta Grid by Nebadon Izumi showing 1000 Avatars of mostly bots but some human controlled avatars in real time (as shown below), this got me thinking again about agent-based modeling in virtual worlds.
