Nice to hear you are interested :-)
Anyway, don't worry too much about this issue for the moment. We still haven't started working with Moodle repository plugins so we know very little about them right now. We will probably know a bit more about how to connect Moodle repository plugins with external services in a couple of months. Basicly, we need to start programming and make some tests, but we need to read the related Moodle documentation first (http://docs.moodle.org/dev/Repository_plugins).
Once we have a clear idea of what we would need from your part and of how to program our part, I will contact you to discuss the details.
