If you are using CORBA connections, you need not to worry about such things.
At least ORBit uses local domain sockets ( == mem mapped ) if both end
connections reside on the same machine. :)
I think mico does this too, but I'm not sure.

Has anybody been checking out some multicast technlogy that could be useful
to loci?
Since loci should be general - purpose and network wide, you might end up at
least sometime with a large number of loci that works with the same data.
Using TCP/IP in such an application would be very inefficient.
And unfortunately, the CORBA standard does not support multicasting. It
would at least be very hard to inplement it. :(
