I would subscribe and expand on that request too. Virtually all of our clients are here in Hawaii in the US, and the likely hood that any of them will ever try to authenticate from anyplace else is really remote. However, we do have a couple of domains where their staff will normally travel to other countries for things, It would be nice to block everything for everyone but have a few domains that we can say "During the next 15 or 30 days allow authentications from this country." and after that time it automatically revokes.
