iPhone GPS for skiing?

[MuGeN]

Ho-kay... So most of us that go skiing have iPhones, and there are plenty of occasions where people split off so I was wondering if anyone knows of an app to find your mates so to speak?

Something like find my iPhone but where you can kindof allow other people to see your position?

Only fallback is that I'm thinking you may need a data connection which might be a) costly or b) unavailable...

Any ideas?

I did think about making an app that does exactly this a few months ago, but I've been busy so haven't had chance

This is the closest i can find to what you need but it's not exactly the best: http://itunes.apple.com/us/app/bindogps-the-gps-group-tracker/id321201843?mt=8
