Differentiating instruction: a big idea?

I’ve been thinking a lot about the challenge of differentiating instruction in the current educational environment and about the potential of applying RSS technology to curriculum and learning.

Imagine a system in which a variety of student data is fed into a managment system. This data would include not only test scores, but classroom observations, reading level, learning style preferences, native language, personal interests, etc. Then the management system generates an RSS feed that drives a customized learning plan for each student. Lessons, projects, and assignments are then given out based on each student’s individual needs.

Anyone know anybody working on something like this?
