[Tracker] Keeping tags synchronized across computers

[Gary Bishop <gb cs unc edu>]

I keep the my files synchronized on my computers at work and at home 
(using Unison). If I use MetaTracker tags to organize my files, I'd like 
to keep those sync'ed up also.

The databases in .cache/Tracker are huge. All I need to sync are the 
tags. Is there a way to transmit only that info?

Thanks
