A fine idea, but a difficult one.

Libarchive and the kernel module have very different
goals and constraints.  Libarchive, for example, cannot
seek, which is required for accessing certain types
of ISO9660 disks.

Still, if someone is interested in tackling this, I'd
be happy to consult on libarchive's needs; if it
is possible, it would certainly help my efforts
considerably.
