Actually, TAO's Load Balancing service (called "Cygnus") puts this
logic into interceptors on the server side. Please see the papers by
myself, Ossama Othman, and/or Jai Balasubramanian at

Would the TAO loadmanager work to load balance between non-TAO orbs?
If not, what would be needed to make them participate as a replica?

AFAIK, there's nothing TAO-specific in the TAO Load Balancing
service. Therefore, you should be able to use TAO's Load Balancing
service with other ORBs. Jai, can you please confirm/deny?

Great, when we get time we will try to upgrade to a newer version of MinGW,
but it is still a candidate. Just keep an eye on the scoreboard, when we
upgrade you will see it there. As you can see on the scoreboard, there are
no issues with the 3.2.3 version

We run all ACE tests, no issues there, we are working on the TAO tests, some
of the tests are able to freeze our build system

There have been some replies. People do have things working on Solaris and
there have been made fixes in ACE/TAO. Could you wait another week or so and
try the x.4.8 or try cvs, see http://cvs.doc.wustl.edu

We have a build with the same setup, we only use the traditional way of
building instead of autoconf, see
http://www.dre.vanderbilt.edu/~remedynl/Solaris10/ for the build results (we
had some issues the last days in the archive).We run on the system all TAO
tests including the IFR_Tests that we ship in the distribution (see
ebug.html for the test stats). I just checked the log, the tests for the IFR
do work on our system. Maybe try the traditional way of building?
