There should be a special "--status-fd n" message (you should only
parse such message because they are not subject to i18n or textual

Have a look at tools/shmtest.c to see how I see the interface.  I
worked this out with Max who wrote GnomePG but due to the fact that he
has vanished from the Internet (any news?) it was never realy tested.

We use shared memory for communication and the caller can request a
block of locked memory for his purpose (to store the passphrase).  
I don't want to use CORBA for this becuase this may have a security
hole but you are free to write a CORBA aware library which interfaces
to GnuPG.
