This idea came about in the front camera threads, but I wanted to break it out for a separate discussion. Now that we have wifi with software 5.0, we should be able to access locally-hosted web pages (can anyone confirm this?). I've got an idea to build a small pcb with some general purpose control lines that will host a "Hardware Controls" webpage which you interact with via the touch-screen web browser. The pcb could be located anywhere convenient in the vehicle since it will be connected to the touchscreen wirelessly. Interactions on the web page could then trigger hardware events from whatever custom hardware you like - for example, turn on that rear fan you installed to deal with the heat issue in the jump seats, or potentially even display data from custom proximity sensors. I don't have version 5.0 yet, so I have a couple questions: 1) Will the browser actually display local web pages? E.g. can you log into your home router from the touchscreen? 2) How fast do those wifi pages load? 3) Does the browser support any dynamic content? Anyone know if it supports AJAX? 4) What are some other uses you could see for control of external hardware through the touchscreen?
