It's not going to unless someone comes up with a SHM message send/receive
implementation that shows significant performance improvements over UNIX
domain sockets.

SHM is good for sharing chunks of large data between apps, but for normal
message-oriented traffic it's no good, because you still need a signalling
mechanism, and latency can be a bigger problem than bandwidth in many
cases. If you have to pass large amounts of data and still need to use
CORBA, I recommend using CORBA to negotiate/control a directly-accessed
SHM segment.
