> I'm not sure about ZFS, but it is good enough for sd(7D) with PCFS. IMO the proposal is incomplete without a clear statement about ZFS, even it it's "unsupported", though I really hope for the opposite: USB storage is the dumbest storage I've ever encountered (so far), yet you can put ZFS on it.
I think the only sure way is to try. Given that the estimated engineering effort for this entire project is 1 engineer-week, I suppose it'd take a couple more days to figure this out. > One possible area of concern for ZFS is device id functionality.

AFAIK in that case a fabricated devid will be stored in the hidden area of the disk. The same problem exists with USB, see "6422928 devid support is needed for usb harddisk". -Artem
