Thanks.

I meant to address these before.  Sorry.

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.
