Hi Michael,
I changed the API a bit, to allow for registration of messages with
name, return type, argument types. I try to map GType's to
CORBA_TypeCode's, to make a more GLib-ish API. You think it's better to
deal with typecodes directly? It would give us more power (all CORBA
types available), but...
A lot of work still to do, but take a look at this if you have time.
Thanks.
