It depends largely on what you try to achieve. When you just need a
protocol for communication between plug-ins and Gimp that are all
running on the same machine, you are free to choose any non standard
protocol you like.
However, if you want to interface with other applications you must
choose a protocol that is a real standard. Basically for the next few
years there are only two real candidates in this area: CORBA and (I hate
to admit it) Microsoft's DCOM/COM+. I have worked with both, and CORBA
is a mature standard with some good implementations.
Other protocols like KDE's DCOP or MCOP as you mentioned are not serious
standards.
Using shared memory is only useful when the two processes are running on
the same machine and you could still define a CORBA interface to set it
up.
So if we want to open Gimp for a distributed environment I think CORBA
is the right way to go.
