As of now, plans are for Snow Leopard server to allow read/write capabilities for ZFS. No word yet if it will operate as a boot partition or not. Snow Leopard Server is supposed to debut with it's client counterpart in about 1 year according to Apple. Developers are being shown a privew this week at Apple's WWDC.
