Rather than verification system I think an optional reputation system. Think of it this way you night be well known and respected amogst a group of friends here but maybe you dont swing with them?.
A reputation system would allow people that you know on the site or that you have met to give you either a possitive or negative rep (similar to ebay feedback).
The thing is the devil is in the detail so
Randoms should not be able to neg you for no reason.
Maybe when you arrange to meet someone from the site you both click something beforehand to open the option up?
Let us know your suggestions? we will then poll the whole site not just the forum users to see if they want it.
