Ok, I just installed the Python/Qt version of DialCentral from extras-devel on the n900, assuming that's the latest/greatest for recent feedback.

I'll play around with this new version, and hopefully find some time to start peeking at the source, to figure out how some of the Python/Qt stuff is working right now, in the interest of getting up to speed on the current functionality, before thinking about 'what if...' functionality.
