More thinking about implement interfaces

Hello all,

Pursuant to my big picture thinking found here: Big picture thinking about implements and integration I’d like to extend the idea of a roll your own implement interface over ethernet. I’m aware that an arduino with an ethernet shield can run a simple webserver/webpage. With this in mind, would it be terribly hard to build an implement interface using HTML as the markup for button placement and text? One could either use the Arduino C, python, or php as the scripting language to toggle pins and read input. I’m certain that there are shortcomings to this idea, but I wanted to get it out in the community to ponder.
