Indeed. The binary port also enables you to send
datagrams. This can be useful if you were to say,
implement an http server off of that port. A datagram
doesnt require a constant communication with the host
(unlike a tcp conection, ie telnet). Thus, we use
cookies for keeping track of users via the web because
their browser isnt in constant contact with us. They
request it, we post it :)

Some drivers, such as MudOS, allow the use of "LPC
Sockets". I am not too sure how well these work, but I
have seen httpdaemons built on them. Not too sure if
DGD does or not (wouldnt bet on it; dgd seems to go
for that "slim" and "powerful" look :), as I am in day
three of "getting to know DGD".
