We were just discussing this on IRC and someone pointed out that you guys had already done this work, very nice.
We were thinking of some sort of framework in QT that would let you write XML configuration files/templates/whatever and that would replace the flash player for the chumby. The general feeling from some folks on IRC is that flash is sort of worthless for the sort of thing we'd like to do.
So with that being said, I guess the sort of thing the QT chumby engine would do is this:
Read in XML configuration files
Ability to specify in the XML file things like, RSS feed, wget, custom data gathering operation, streaming audio, etc. So you have the ability to define the transport mechanism for getting the data off of the internet and onto your chumby.
Once you have the data, you need to tell the QT chumby engine how to display it. For instance, if it is in RSS mode, you might have a picture that goes along with the text, and the QT chumby engine would know that and display it properly.
It is hard for me to write the entire spec off the top of my head like this, but I just wanted to throw a few ideas out there and see if anyone was interested or thought this was a good idea.
