I understand it’s possible to combine multiple sims to create your own grid, what I was talking about is combining your sim/grid with other sims/grids out there into a global grid, like the web. This is what I understand the http://www.osgrid.org/ project to be about. I don’t think we are disagreeing on this.

I will still say though that a virtual world of 1000 students will be far less interesting or resourced than a global grid of millions. Wouldn’t you like your students to access projects like the NASA-funded International Space Flight Museum?

This is why we need open protocols that allow us to connect sims/grids and have a web-like model.

Are you aware that Linden Lab plan to open source their server software?
