Has anybody written a program to monitor NeWS network connections,
that runs in the server? Sort of like newsmon, and sort of like
Brett's security popup. A NeWS process could listen on socket 2001,
created with "(%socketl2001) (r) file", and wait for connections. When
it gets a connection, it calls "acceptconnection" and forks off
another process to serve that connection. The 2001 server process
would open *another* socket to regular old port 2000, with
"(%socketc2000) (w) file", and copy data back and forth.  (You'd have
to fork a process for each direction. Note: don't depend on
bytesavailable being right when it says 0.)  Each server process could
put up a control panel, with stuff like a scrolling, decoded (i.e.
un-CPS-byte-encoded) log of the information passing in each direction,
total byte counts, connection age, average bytes/second, remote host
name, maybe optional scrolling graphs of various statistics over time,
or a histogram showing the number of occurances of each character.
Another nice feature would be a way to put a stopper in the stream in
either direction (and a way to make new connections come up initially
stopped), and a display of the buffered data behind the stopper. Press
a button to drip one character through, or a certian number of
characters, or to unstop the connection. Open the stopper just a
little bit to drip characters through slowly. How about a way to
insert strings and arbitrary bytes into the stream in either
direction, in front of or behind the stopper? And a search feature
where the stream would flow until a certain character (i.e. newline),
or a pattern was encountered!  If anybody has or makes such a beast, I
sure hope they give it away free, because it could help solve a lot of
problems!
