The creators of Habitat (Chip Morningstar and F. Randall Farmer) now have a blog ! It's really nice to benefit from their experience. Their paper "The Lessons of Lucasfilm's Habitat" should be considered as a primer in research about multi-user environment.

- A multi-user environment is central to the idea of cyberspace. - Communications bandwidth is a scarce resource. - An object-oriented data representation is essential. - The implementation platform is relatively unimportant. - Data communications standards are vital. - Detailed central planning is impossible; don't even try. - You can't trust anyone. - Work within the system. - Get real.
