LMS - learning management systems

I'm looking at LMS for some new content that we are creating. For one site, I've picked Joomla. That is really a content mgt and community system.

My more ambitious projects require my own cms. I'm reviewing them at http://sourceforge.net/search/?type_of_search=soft&words=lms

Leading contenders:
- create my own
- joomla or jooml with lms
- druple
- moodle

I have a few sets of requirements. Quickly evolving....

1. Course mgt. I want the students to see the upcoming activities in a visual way. They should be able repeat what they've done .....

2. Student record keeping

3. Roles for admin, course creators, course teachers, parents, students. In fact, I want to be able to create new roles based on whether I want to give them access to:
- create accounts & grant permissions - globally
- create content
- create students
- look at records
- be a student
- ohmygodthisisgoingto be a long list...
