How does this work exactly? Downloaded and installed the beta, I don't see a pref for bookmark location anywhere, and doing it the normal dropbox way, with symlinks isn't working either.
It's described in the link that obfuscode included above, but it's just in a narrative so it's kinda buried. To summarize, you drag your Yummy FTP -> Bookmarks folder to your dropbox, then make an alias there and drag it (the alias) back to your Yummy FTP folder and rename the alias "Bookmarks". Yummy FTP itself will follow the alias, and Dropbox will make sure the data is synched to whatever machines use that same Dropbox account. I put my Bookmarks folder within a sub-folder of my Dropbox so that I know what application it goes with (since the name "Bookmarks" would otherwise be pretty generic at the top-level of my Dropbox).
