In the exhibition, there's a thread about CGI forms and controlling it.
But me and Plastbox stole it and began discussing using PHP

Thar ^^
It has all the basics, Arduino code, PHP Code, sample "Proxy" code(Written in VB)
The thread is somewhat of a mess, with all the code, but in a week or two, when my Arduino(Finally!) Arrives, I'll make a good copy writeup on the playground.
^^ My site(Down as of June 11, not sure when I'll be back up, at least a week, not living at home, and my friends ISP blocks web servers)
But yeah, if you have Visual Studio, know some PHP and Arduino language, you could quite easily modify this to facilitate your needs.
I have also modified(but not yet posted) the VB backend proxy with an Icon, and allowed it to be Sent to the Tray.
Enjoy.
