The problem with MiG is that it does more than just marshalling and
unmarshelling the arguments and calling mach_trap(). I doubt that
using a mig2idl converter would solve our problems here.  IMHO, the
canonical way to do this is to switch to synch IPC completely (this is
probably even possible with mig) and take care of the few cases where
notifications/callbacks are needed. Once this is done, switching to
IDL (or any other interface definition language) would be quite easy.

I'm not 100% acquainted to the subtleties of MiG though, so please
take this with a grain of salt.
