That would be great. I'll be posting the announcement about it 6 May. If the day comes and you have any questions about how to proceed, please feel free to email me directly. 

Cool Cobalt World? I don't have one. I have a default space that looks like the holodeck at night on the Enterprise. Cobalt also comes with a very beautiful world. I got ribbed once for not interior decorating. But then I go and put a floating triangle in my holodeck, and people can't join my space. Seems you need to use 3D Studio Max or Sketchup or something to add stuff to the world. You don't need a cool world. 

Windows 7 or Ubuntu? Which is more stable? That's a great question and one I'm not best suited to ask. I'm on a Mac. But really, that's what the Cobalt VR Meetup is all about. We use Skype IRC and that's solid as a rock. Then we can try stuff in Cobalt to see what's working and what isn't. Get Skype and OpenCobalt and join the dialog. It's pretty cool stuff. Your students will love it. It's Primo, as in the beer.
