That sounds more promising, but if you're putting them on RF for 
travelers, then I wish you'd consider putting them on APRS for all 
travelers.  There's more APRS users than just APRS RF radio owners, and 
I'm sure some of us would appreciate seeing them beacon on our mobile 
APRS-IS clients as well.
