No, there is no shared memory transport in omniORB. The paper you refer
to was describing some experiments that were done with shared memory,
but that code never found its way into the main omniORB distribution.
The main reason is that it's awkward, and not actually very efficient to
use shared memory when you have large bulk data to transfer.

If you have access to (or can implement) a stream transport that allows
data to stream from one process to the other, it will be relatively
straightforward to implement a new transport for omniORB that uses it.
