Right now I am in the US, in Washinton for the Federal Consortium of Virtual worlds as part of a delegation from e426.org and the IEEE to discuss virtual environment standards and eco systems. This is all very cool and forward thinking as twe are not just talking about file formats but about human experience.
Rather pleasingly though Dave Taylor has a poster session here and did a demo yesterday of the Missive Project. Around major incident simulations. This is a project very dear to my heart as various aspects of it are things that I built as Feeding Edge Ltd.
It is worth reading his post(er) and I am sure I will talk to a few more people at the conference about it.
Lots of the environments send and receive data form various sources. A web menu drives options, a remote virtual patient in a scenario model responds. I do all the brokering and message aggregation and interpretation in the middle. Old habits die hard, this was SL/opensim middleware.
It is great to catch up with friends old and new from the industry but if you need an ROI on virtual worlds (do you want to sit like this for 8 hours 🙂 )

Also I discovered on the flight over just how pitiful the 3DS battery life is, no wi-fi on and it only lasted about 3.5 hours of playing ghost recon! Not good. Though it did make me watch The Social Network on the seat back TV instead, which was much better than I though it would be.
Anyway, off to the conference.
