Making an application like this mobile is a bit more involved, not so much the code but designing a good user experience. Mobile use on cc.com has increased dramatically to 10% of traffic (this includes iPad which accounts for 31% of mobile), the question is are people actually trying to find info on the road or are they like you in a meeting, on the bus, which you can't really answer without flat out asking like I did above. If it's the later then I'd be less inclined to make a mobile friendly version.
