Sure. Think of it like a persistent database connection in
Oracle, where the listener is on socket 1521 for everyone.
The persistent part saves you from the 3-way handshake when
you use the same socket on subsequent page requests. The
only caveat is that you can only do one thing at a time,
but this is typically handled for you at a lower level in
the form of a queue. If I remember correctly, you can
specify the size of the queue in your function call(s).
