[erlang-questions] Unicorn-style load balancing in Erlang?

Does it mean that we can have Unicorn-style load balancing in Erlang?
If so, are there any existing servers or libraries making use of this
feature?

For those who are not familiar with Unicorn [1], it is a traditional
UNIX prefork web server. Load balancing between worker processes is
done by the OS kernel. All workers share a common set of listener
sockets and does non-blocking accept() on them. The kernel will decide
which worker process to give a socket to and workers will sleep if
there is nothing to accept().

btw, I also posted this question on StackOverflow [2] but no active
responses there :-(
