OK, I have inspected the encoded IORs and I can see that there is a main
host entry in the profile plus a number of ALTERNATE_IIOP_ADDRESS
entries encoded as tagged components.

What I can now say from experience is that the Sun Java ORB does not do
it. It only tries the main host entry in the profile and ignores any
ALTERNATE_IIOP_ADDRESS. I currently cannot say if this default behaviour
can be changed easily.

I am now hoping to get away with an interceptor attached to encodeIOR,
which changes the host entry to the one relevant for the respective
client. Not nice but it seems to be the last resort in my case.
