Just had an idea, as if Logos needs any more. You guys are putting together a lot of different things e.g. web interfaces, reftagger, Android, Iphone, etc and I'm sure you don't need another, but....I can't resist.
Yesterday i read about the IPhone App Word Lens. You can point it at a spanish sign and it translates the phrase into English instantly. I would love to have my IPod Touch on with an instant verse parser that operates the same way. Point the camera at a reference, and the text instantly appears on the screen. I could be reading a paper book (I do on occasion do that still), point to a reference and the text is just there.
