Well, my big concern here is performance on a small device. I haven't
done much testing yet, but some operations seem quite slow; I won't
really know until I get it all going.  The format of the ~17MB roofs_data
takes 3-4 minutes, but that's a one-time operation after sysupgrade.

In my colleague's case, he used AES and was able to make use of the hardware
acceleration.  I imagine that fscrypt in JFFS2 would avoid a lot of overhead
too.
