I implemented something like this as a shell script that was called as a cgi
from a web server. I don't have the scripts now, it was ages ago. But i
would recomend saving your self the pain of trying to write your own client,
server, and a protocol for them both. Most people have web browsers nowadays

(btw - if you where going to go the snmp route ucd-snmp can call a shall
script whenever a particular oid is called so it's pretty easy to get info
out of your machine that way).
