Audio Capture Component?

It seems to me like this would be a very handy component. If you don't know what I mean by it, let me explain. What I want to build is an application that runs on a tablet PC but sometimes requires the user to enter extensive notes. I am trying to avoid requiring anyone to use the keyboard to enter this information. What I would like is a way for the user to speak the notes, capture it as an audio file, and store it on the file system and eventually back on the server. I know FMS would allow me to do it but since this will be an AIR application used by people "in the field", they may not always have a connection back to the server at the time of the recording which is why I need to store it on the file system.

If this doesn't already exist, it might be my next pet project.
