I've also written a little daemon that I call procd. It is a simple
socket based app that listens for a connection on a specified TCP port.
You telnet to the port and type the name of the file you want to view. It
restricts the files you can see to those available from /proc. So if you
want /proc/cpuinfo that's exactly what you type into your telnet session
and you get the results right there. There isn't any reason why another
program couldn't be written to communicate with this one. The output from
the file requested continues until you see a '.' on a line by itself, much
like the termination of a DATA segment in SMTP, so it would be easy to
parse.
This runs as a nonpriveleged user also, no need for root.
I don't have this up on the web yet so if anyone would like to see it
just drop me an email. Its GPL'd, as it should be.
