Just wanted to mention that you
don't need a dedicated server to run this plugin.
Several clients are hosted on hostgator and doing fine.
Unlimited domains 
You only pay once!
You
can use all sponsors at once and they are randomly ranked in the DB so that
no sponsor gets pushed down in the page results.
All search functions/tags work.
Offline model's page will display offline message rather than "404".
No extra server storage space needed because no images are ever stored.
