for those hard-hat like me.
First, it is an open source project. The license is even more liberated than GPL. You can basically do anything with the software except sueing the developers and keeping it open.
Second, it is a peer-to-peer collaboration platform with nice 3-D interface. Yes, 3-D interface.
Third, it is cross-platform, of course!
Fourth, it is in pre 1.0 release at the moment. That's why you find it out here instead of the mass media.
I am going to try it, downloading all the three versions: Windows, Mac and Linux.
