Sync feed database via Dropbox

[koreyhinton]

I would like to access the same feeds on different Macs without having to do the opml import/export process each time. I followed the directions at http://www.vienna-rss.org/?page_id=96#How_do_I_move_my_Vienna_database_to_another_folder to move the messages.db file to my Dropbox folder. The problem is that once I do the same setup on a different Mac it removes all the feeds and syncs the empty db back to the other Mac. Is there a setting or trick I can do to get this to work? Or is there a different way I can automatically sync the feeds?

Thanks!
