Here in Germany we do have Face2Face as age verification.
I talked to dzinerbear about that a while ago and he was very stunned that if he wanted he could not get into member areas under .de domains where the owner is german since he could not pass the F2F-verification at a local post office or via SCHUFA (company that holds bank account data, personal credit data and such).
They say that it cut revenue by 70 to 90% in Germany.
