I can also write (3) without too much effort (have spent lots of time the
last months developing a small library that takes most of the pain out of
developing AES applications) if such a thing doesn't exist already. The GUI
will be easy and can be done in a couple of evenings, it's handling the
configuration files that worries me. Writing my own code means duplicate
efforts every time an option is added to the configuration files. I would
prefer to have the configuration for both the kernel and XaAES available for
both reading and writing through a proper OS-call.
