fwiw, one disadvantage of this approach is that it relies on the existence 
of a particular file at the root directory. The problems with this method 

* It assumes that "one hostname = one web 'site'", where 'site' is an 
administrative grouping. There's no way to delegate responsibility closer to 
the user of the functionality. 

* It pollutes the URI namespace, which should be under the control of the 
site's owner. 

This is W3C TAG issue siteData-36. References:

If WHATWG was to pick some of this up, I think that they should try to avoid 
the problems mentioned above, or, if at all possible, work with the TAG to 
help explore some possible solutions to the general issue.
