I don't see a response from Greg so I'll try to answer this (see below).

Pls see the follow-up question inline

No, the wire protocol only specifies the message structure.
The transport protocol is currently TCP/IP, but this will probably
change when I finish adding remote support. It's likely that one
of the options will be to tunnel across an ssh connection. Also, a
static port number is not used. Eclipse generates a dynamic port
number which the proxy connects to (it's passed as a command line
argument to the proxy.)
Can you elaborate more on the process on how this connection should
be established? From the spec, it gives me the impression that
backend proxy should act as a server, but, it is "command-driven"
by the eclipse front. Aforementioned (and the code itself) indicate
the proxy does connect back to Eclipse front (a dynamic port as
server port?).
Currently the remote proxy (remote from the Eclipse instance) must be
started from the command line by hand or via an exec (if on the same
machine as Eclipse is running). The command line contains the port
number that the remote proxy is to attempt to connect to. Once a
connection is established, the remote proxy listens to commands from
Eclipse and then response to them.
Greg has been working on a way to start up the remote proxy from
Eclipse using an ssh connection. He is also considering using the
ssh connection as the "wire" over which to send commands and receive
events. In this case the TCP/IP port wouldn't be used but the wire
protocol would stay the same.
Hope this helps,
Craig
Thanks
