Trash talk @ COTA ?

I was talking to Dave about this at TWS and thought I'd see if some/most of you are interested.
We talked in years past about having some trash talk and other audio snippets to play over top of the EOY video.
One of the features of our system is a voice/chat capability and I thought I'd make a standalone iPhone/Android version that everyone could use during COTA (and future races if it works out).
It would be a "partyline" that I could record so we'd get trash talk and such during races.
The app would autoconnect and be vox (so hands-free).
All you'd need would be your phone and a headset with mic. You can use the headset that came with your phone or you can get a set made for helmet (there are decent packages on Amazon for around $5 - I am using a set fro abcGoodefg).
I'll need to do some work to create the standalone but wanted to gauge interest first.
