Well, "effective" is a relative term. I guess I don't see this as having any ultimate solution; it's an arms race. The question is whether doing so would give enough marginal value in and of itself (which might even be neutral value, but it would be better if it were at least slightly positive) to get us to the next step where we can possibly apply third party vouching, authorization etc to the mix. Thus, my question -- and I think Harald's as well -- is mostly a *tactical* one, not a technical one. IMO, it's the tactics which will allow or inhibit forward progress. Mike
