That sounds great :)

There's already a built-in mechanism for this (available in both MS.NET
and Mono). You can replace everything that correctly (i.e. use the
factory methods) use Rjindael/Aes (or most cryptographic
implementations) by using machine.config file.
As such you only need to concentrate on your own, AES-NI,
implementation. I.e. something that derive from Rjindael or Aes.
p.s. at some point, once we get a few different implementations, we'll
likely want something to help users. I got some notes about that... I'll
try to dig them out this weekend and post them.
