Why can't you use a GUID as discussed on a different thread.

Changing the way arjuna's UIDs are structured is a big deal and a) will take more time
than we have before component freeze for AS GA and b) is not worth the hassle in light of
the number of alternatives available.
Its a waste of resources (a file handle) to open a port or lock a
file.
Feel free to provide any other implementation of process uniqueness you happen to like the
look of, since the two we provide don't seem to meet with your approval. As long as it
returns a value 0-65535 that's uniq in the scope of the O/S it's running on it
should be possible to plug it in without too much hassle.
