Rob's comment nailed it...
For your last bit "Don't we all use SSL tunnels for this already?" - for data in flight yes - this is for encrypting data INSIDE the tables while at rest. This seems like a good feature to have integrated straight into the DB engine without having to take an overhead hit of encrypting everything, but maybe not. I'll need to do a lot more research before I come to a conclusion on it.
