Yeah, if the Server is a php box, then the Controller interface can be made in
a web page.
Then if the communication happens from Apache/PHP - > client via sockets and
some simple byte oriented or even human readable string orientated protocol,
and the client app/process watchdog on the (n)_random_client boxen are written
in C/C++ or PHP, depending on what's appropiate, you should have a fairly quick
... to turnaround time... to borrow some newspeak from a random marketoid type.
Of course, it might be worth your while to encrypt the protocol transaction,
with something simple like crypt();.... somebody somewhere would try to spoof
the protocol transaction I'm sure... saving himself ... 1.65 of interweb charges.
