Hey pearl62 and Koffie,
The plugin is still sitting patiently, waiting for me to actually get off my backside and get the carPC going. 2 weeks ago I finally gave up trying to build my own
VWCDPIC which I need to interface my head unit with the PC and I just
ordered one. I've been a bit distracted from this project for a while but I've finally got some finances crying out to be spend so I can actually get back into my plugin programming.
I like your thinking Koffie, It would require the addition of some analog phidget inputs as well as an output to control the ventilation button but it is most certainly possible. It would be tricky to add customisable event functions but not impossible... Hmmm. I could allow you to 'program' actions to the inputs through the config screens just using basic keywords. I'm hoping to set up the application to recognise all of the different types of phidget interface kits so this wouldn't be much of a stretch beyond that.
I think you have given me the motivation to avoid real work and responsibility and do my own thing instead!

Yay!
