Well as I said there seems to be a definite interest in exposing logs from the TelHosting software, but it's really only going to be a sample of the "real" traffic. Unfortunately with the DNS network we have there's no way to propagate statistics back up to the top. Client software could log usage data and make that available (perhaps they could even sell it to .tel owners).
It's somewhat beside the point anyway - all me and my advertisers really care about is measuring clicks/calls, and that is easily done.
Say I'm building a directory of plumbers. I allow them to list their entries in my directory for free, so there's absolutely no cost barrier, but I want to charge them for higher rankings inside the directory, or placements in more premium areas of the directory, then the best way would be to do it on a CPC basis. To measure this, one must use a proxy between the directory and the terminating channel, for example;
Joe The Plumber's phone number is 1234-111-111, but he's paid for some kind of premium service inside the directory, so actually his number gets listed publicly as 1234-222-222, which is a virtual number (provided by voip.ms or a competing provider) that simply redirects to 1234-111-111. Each call to the virtual number gets logged, which Joe then gets invoiced for. One might also charge Joe for making this virtual number a toll-free 800. He only pays for sales leads that the directory sends his way.
Or maybe, since we live in such a crazy ass world, Joe The Plumber has his own little media empire, and his listing is a premium $5/min phone line that his fans can use to call him up and leave insane rambling messages. We do a revenue sharing deal. Beautiful.
