I don't think that chumby is the way to go for desktop applets. It's allright for what it's meant for and it is nice that i can watch a chumby channel while the n800 is sitting on my desk - but that's about it. Especially for a mobile device i think it's worth to put some time into developing custom widgets/applications. Certain constraints (battery life, screen size, user interface) can only be addressed that way.
