Well, that would explain why an iDevice needs a control chip to charge - on the scale that USB works at, that's a serious amount of juice (small wonder stuff like this jacks up your electric bills over time).
Okay, so the USB Hub would have to be 'hardy' enough to handle the kind of demand that multiple high-drain devices would place on it. This would be why most hubs have their own power supplies to begin with.
One other question: what do we know about these control chips in question? Specifically, how many ports can one control and what is its physical dimensions? If it is limited to just one or two ports and the chip is the size of a... dime I guess, then I might wnat to offset the size by including more than the usual four ports. How many ports would you think are too many?
