>That innkeeper would have used the signal of how the visitor looks Not like that ever backfired. >inkeeper would be able to tell assuming that he have photographic memory and visitor did not change his looks by any way (shaving, getting scar etc.). if you have to refer to 'looks' you have IP - it has exactly same power as signal as looks. >Also your metaphor is not great because WEI can only happen after the first page load since it requires the site to use javascript to use the api. for user that is irrelevant point.

The idea that server owner should get any say about this is simply intrusive.
