Has anyone tried synchronization by Dropbox?

[David Munch]

By using a symlink to ~/Library/Application Support/Camino?

Having tried out Chrome for a few months, I have to say I really like the synchronization between two machines, and I'd like to have it using Camino.

That would be fine, as long as quit Camino, I think.
Camino reads most settings (pref file, bookmarks, etc) at startup. If changes happen to e.g. the bookmarks file while the browser is running, you probably risk some data loss.
