Interesting. Did you have any thoughts on how to do it? (mounting of the radio, earpieces, etc).
The thought came to me at Daytona, when I was scaring myself silly, thinking I was in a close battle for my first win ever...and then I found out from my crew that I had a 6 or 7 second lead the whole time. Could have saved myself some work. ;)
Also, I came into possesion of one of those Motorola things for free recently, so the idea has been reborn. :-)
