If just your team wants to hear what the coach is saying, it's easy to rig a mic up so that it records the match. In the past, I've made a loose necklace through my mp3 player, then draped it over my coach's neck. Turn on the voice recording function pre-match, then line the audio up with video taken of the match from someone else. You end up with your coach 'narrating' video of your match, and it is pretty cool.

Probably not ready for prime-time though. Things that get said on the field should probably stay on the field.
