I have been planning to install multiple blog for multiple bloggers on my network. Now I confuse which project shall I choose. There are lot of wordpress projects. Alternative projects and plugins which provide some level of multi-blogging facility are :

Lyceum
Developed by ibiblio.org, Lyceum is a stand-alone multi-user multi-blogging application designed to handle 2 to 2,000,000 blogs.

WordPress MU
WordPress MU is an official branch of WordPress that is designed for managing and hosting thousands of blogs instead of just one.

Virtual Multiblog
Stephen Rider’s system that uses a modified config file to call different blogs based on directory or domain.

MultiSite
Ruben’s attempt at a WordPress Multiblog

Multi Blog
The project of a small group of WordPress users. Information about its development:

Multi Blog Hack
Another multiple blog hack for WordPress. One installation, each user has his own theme, blogname, description, links, etc.

You can read more information about that projects at http://codex.wordpress.org/Installing_Multiple_Blogs

Now I’m trying to get more information about some features and known issues of them. Any advice or suggestions ?
