Nice DeanŠ

I'm not so sure we would run the server, but we'd definitely be interested
in the logback adaptor.
(We would then just access the data via Virgil (over REST), with a thin
javascript UI)

Let me/us know if you end up putting it out there.  We intend centralize
logging sometime over the next few months.
