Now that I have figured it all out, I would like to rate this plugin as it deserves at least one rating. It works as advertised and is a solid service and app plugin. I am not sure why there aren't more people jumping all over this, but I am sure they will once they figure it out.

Yes, you have to sign up for the online service, but at least it is free and pretty darn cool to boot. Try it out, there are no strings or strange loops you have to jump through.

I have also figured out the routing functionality. If you want certain photos going to certain sites (eg. personal flickr and work flickr), then place unique @tags in your keywords field in Aperture. The key is not to leave the "Add keyword to uploads online: ... " field in the export dialogue window blank.

If you leave that field blank then a bug will not recognize your Aperture keywords. I have notified the dev about the problem, so hopefully we will see a fix.
