Something awesome for the db, would be to run a dummy dns server sorta like maps/orbs/whatever, charge a buck or two a month for access to it, and we just do a domain lookup and see if it resolves to a dummy host.
(easier than dumping/sending/importing a big db dump all the time)
Of course, I may be thinking the list is bigger than it actually is.
