Time Machine & Lion

There will likely need to be a public beta firmware that adds Netatalk 2.2 (this update includes AFP 3.3 and a large number of other things as well) before a production firmware with it included is released. I would suggest keeping an eye on the Mac OS X forum as well as the Public RAIDiator Beta forum.

@stannenb We'll have a release for x86 Wed. Sparc release will follow at a later date as we're working out some issues there.
