design/implement a secure DNS-like "map string to bitcoin address" system (so I can send bitcoins to "gavin@acm.org")

The solution for sending coins to people is at http://bitcointalk.org/index.php?topic=3427.0
I envision adding a "wallet" tab to the client, which lists every bitcoin bundle in wallet.dat, and if you double click any bundle you can: (1) copy the private key for that bundle so you can email it to someone, (2) split out a different amount, (3) combine with another bundle, (4) reissue. Very similar to that other digital currency ecache.
