Thanks, but I obviously wasn't explicit enough.

I've read that and done it by hand -- which is why I think I can
program what I need.  However, it's some way from a Unix daemon that
starts up, queries other systems that might be running and asks one to
add_node it or otherwise starts orber itself, accounting for races
with an identical box rebooted at the same time.  I expected this to
be a fairly common idiom, but maybe it's rare to use Erlang-based
services like this.

[Being able to provide a properly-replicated server at all seems to be
a fairly compelling use of OTP; I've had no hint here that there's a
Java-based equivalent, and everything has to be written in Java.]
