Dynamic disk mirroring and parity striping (RAID 1, 5) in Vista?

Sorry for this cross-posting, but I think this question belongs here more
than in Hardware Devices.

I can't find mention of this anywhere. Does Windows Vista support mirroring
and parity striping (software RAID 1 and 5) for dynamic volumes? Or has that
feature once again been crippled out of the user versions of the software?
(End users do want to parity stripe their disks, Microsoft!)
