Just be careful about the 'crypto-with-a-hole' rules..  You need to show
that the interface is general, and can be used with anything, not just
something for the crypto.  For example, you might want to make something
that does e.g. deinterlacing, or some other real in-place data
transformation.  Yes, I know we already have mythtranscode, but for
something like this you may want to take that a step further.

Just my $0.02 as a long-time crypto guy.
