No it does not. For normal CORBA requests, multicast would not be
useful, since a CORBA request has a single target object. Multicast
could be useful for event or notification services which are layered
on top of CORBA, but we have no plans to support such things.

What in particular do you wish to achieve?

I'm not sure how this question is related to the first one, but yes,
omniORB can produce persistent object references. In omniORB 2.x,
using the BOA, you have to use an omniORB proprietary API. The best
example is to see how the Naming service implementation does it.

With the 3.0 pre-release, using the POA, you can use the standard POA
API.

Cheers,

Duncan.
