This sounds like a great idea. Sure there may be competition, but that isn't a reason not to do it. You may want to take a look at how Twilio handles in-browser audio recording (even though they offer something different). Basically, you insert some JS into your page, then the audio is streamed to Twilio, and then Twilio does a callback to an endpoint you specify (with meta data, the URL to the file etc etc). What is also great about this is that I can serve the files right of their servers and not have to worry about it as a developer. Best of luck with it!
