You're right. The right trail is unix domain sockets, that's how
programs like xterm connect to the local X server without any
fuss. The discovery that common Linux boxes don't listen for X
connections via TCP at all means TCP sockets can't be "bomb proofed".
I added 'unixdom' to the jungerl. All you have to do is apply the
previously posted patch to ex11 and then run:
jerl -pa ex11/lib ex11/widgets -s example0 start
and it should be bomb proof.
(Add jungerl/bin to your PATH to get 'jerl'. It is a wrapper
shell-script around 'erl' that adds all of the Jungerl applications to
the code-path, thus making unixdom sockets available.)
