Adding a small, open source version of the image access code would be
another possibility; you probably have a public spec of the format, and
including support for your format in a QEMU block driver doesn't change
much.  Who knows, it may even bring cheap advertising. :)

QEMU has several entry points for the block driver, and the once with
lower performance are extremely easy to implement (see block/bochs.c).
In theory it could even be read-only, though we would have problems
testing it and this may mean bitrot.
