Personalized widgets

I have started programming a few simple learning activities that can be added on web pages flex labs. They are all designed to be easy to embed.Here is an example.







This is simply a matter of specifying parameter values in the embedding code (pretty much the same way youTube does). I won't be in a position to provide any reliable service for another few weeks (I am about to migrate to the other side of the planet). But I would be highly interested in hearing of expression of interest about what widgets should be created to support educators (preferably widgets that don't exist yet).
