It would be really interesting to have a mobile app for the auction hall for iphone, droid, etc.

There might be an advantage to players with smart phones being able to use the auction hall while not in game. Perhaps a limited number of bids per hour, or a CE charge for a number of bids would suffice to balance between smart phone users and non smartphone users. I mean something along the lines of 1 CE for 10 bids.

Either way, it would be pretty cool to be able to keep up with my bids during work and so forth. (not that I have a ton of free time :D )
