Every piece of coding is custom. As long as you can write code properly then it makes no difference. The only thing I am concerned about here is the bluetooth simply because of the range but heck swap it for an Xbee. And if Robochallenge can wire up a Wii then why not an iPad? Or a Xbox controller? Playstation Move? Lewis Hamilton drove his F1 car from an iPhone 3GS, at full speed around Silverstone!

And 2.4Ghz isn't fool proof either. My machine ended up getting stuck in a high speed spin during testing due to the Wifi at uni. It has happened twice in exactly the same location. The one time I was there and it didn't happen was because they had turned off the Wifi to do a software update.
