A simple mind-game (germany saying, doesn't translate very well into english) :
Would for our stuff (DCOP, XSMP) a simplistic GIOP implementation based on Qt
container types and QSocket and friends be sufficient?

(assuming we don't need the latest CORBA::DynAny, ORBit-IDL, etc. features for 
our stuff)

Of course we don't have such a thing at this point and ORBit is here and now and
probably a seriously feasible solution. But _if_ GIOP would be sufficient....I
would kind of like the idea... would be very interesting to hack something like 
that.. :)

Bye,
