Adam,
A month or so ago this topic was current. I spent quite some time and
finally dribbled out some stuff. Yes does work through NAT. NAT is
only a concern if the originator is not known- otherwise we can know
it's there protecting us and then forget about it.
The only part I didn't check is whether event connection is originated
by client or server. I do think the server advises client of event
port during connect handshake and then leaves it to client to initiate
a connection.

Search archives for my dribbles or I can send off list
