Would GPS signals be sufficient? Sparkfun has a wide variety of GPS
circuits, and they're finally coming down in price.
Potential problems with GPS include precision, the initialization period
(up to 40 seconds, I've heard), and satellite visibility. The GPS
advantage is a fairly low price due to commoditization.
There's also AGPS, which improves the precision but increases the price

Sparkfun could be the right place to ask. They've designed a lot of
circuits and they probably know a lot of good designers.
I should say that I've also wanted to build a pair of circuits that
measure distances using RF signals. With triangulation, and if the
measurements happen often enough, you could make outdoor video games.
It would be better than a Wii!
