Diving into Sakai project

I'm diving into Sakai project with intention to evaluate it as Learning Management System for my University.

Description from original web site:

"Sakai is a set of software tools designed to help instructors, researchers and students create websites on the web. For coursework, Sakai provides features to supplement and enhance teaching and learning. For collaboration, Sakai has tools to help organize communication and collaborative work on campus and around the world."

It's mature and well supported platform, targeted for large institutions. It uses some parts of J2EE technology with light approach. It's built on Spring framework and can work on Tomcat server.

Probably there will be need to customize some parts of platform to conform local requirements, so I have to check architecture and enchantment possibilities.
