I once just about socked a smarmy kid at an Office Max who told me ear mics didn't exist because it would be illegal for anyone to record their calls. It simply isn't. A functioning app that can record both sides of a phone conversation would sell quite well with journalists alone.
I think that what the largest issue is, lies in the fact that there are a handful of people who would use such devices and apps illegally. Yes, it is not illegal to record a call, but it is if both parties don't consent to it (unless of course there is a court warrant involved). I'm sure that most devs would feel that, even with disclaimers and warning, they could be held liable if someone was caught using their app illegally.
I could be wrong, but that would be my biggest concern.
