An interesting test would be to see what sort of CPU hit you encounter
as well.... with SSD's, a 12% throughput hit isn't all that horrible,
but I'm curious what impact it has on CPU doing the
encryption/decryption on the fly. Will writing files cause my MBP to
spin the fans up? Writing an encrypted DMG sure does....

I installed FileVault on an older MB Pro (that happens to have a Momentus XT Hybrid drive in it), ran XBench Disk Test, then enabled File Vault encryption and re-ran the Disk Test benchmark. FileVault inflicted a roughly 12% performance hit. This is not a scientific test for many reasons, but it's probably a good first blush.
Does Lion support FileVault encryption on external drives, too? How about Lion Server? (Now that it's out, I guess we can talk about such things, right?)
