There's no way to ask omniORB itself to do it, but you can write code
that directly manipulates IORs to have that effect. For inspiration,
there is some C++ code that messes with IORs in the omniORB connection
management extension in
src/lib/omniORB/connections/omniConnectionMgmt.cc in the
makeRestrictedReference function.

If you're using Python, you can access the innards of object references
by marshalling the reference into a buffer with cdrMarshal, then
unmarshalling it again using the IDL definitions for IORs. I've attached
the IDL you need and some simple code I had to hand that digs into an
IOR. You should be able to use it as the basis for something that
modifies the IORs as you require. After modification, you can do the
cdrMarshal / cdrUnmarshal in reverse to turn it back into an object
reference.

Cheers,

Duncan.
