flickr sync

[Randall Smith <randall tnr cc>]

I've started playing around with f-spot 0.1.11 and flickr as I'm 
attempting to tame my photo collection and share select photos.  I'm 
trying to prevent dual-maintenance of photos so I'd like to maintain all 
tags, comments, etc in one place and have it synced elsewhere.  My 
original thought was to tag photos I wanted on flickr with a 'web' tag 
and only export those photos.  That's great for the first export, but 
after that it doesn't work because photos already uploaded would be 
duplicated.  The most simple solution I can think of  would be to record 
photos already uploaded and add an option to the export dialog to 
exclude those.  Thoughts?
