Topic: iGoogle-tizer / iGoogle Gadget wrapper
One could compare iGoogle to Chumby purely as a medium of information display/exchange, and they can compare well.
One Google Tab => One Chumby Channel
One Google gadget/RSS Feed => One Chumby Widget
If someone wanted to duplicate their iGoogle experience on their Chumby, they would need at least a Google Gadget wrapper widget, something that can display an arbitrary gadget as a widget.
The next step would be to have tools that migrate one or more items from an individual's iGoogle page to the Chumby, or even synch them up.
Obviously this isn't a small project; it would take a roomful of interns at a Summer of Code with a couple of cases of Bawls to get done.
