Thanks.

I don't know, I'm interested to find out. I just benchmarked that.
Actually it should work very well as a NAND-only fs. Also you do get
something like XIP with NAND. If you boot an XIP AXFS image on NAND
or a blkdev it will copy that XIP region into RAM and "XIP" it from
there. I think this will make it very good for LiveCD's. Though we
just (minutes ago) realized our testing of that feature was flawed, so
no guarantees.

It could be. I plan on implementing support for brd. That might work nicely.
