Log:
Okay, I decided not to wait..

Here are the beginnings of what some people have envisioned as a generic storage engine..

The main reason for this, is to genericize (yes, I said genericize) voicemail,
but it would be useful in many other places as well.
Imagine if you will..  s,1,Playback(imap://tt-weasels)
