Its trying to deliver de-referencable names, where the name (denotation) 
mechanism is loosely bound to the resolver mechanism. As you know, an 
http: scheme URI delivers both albeit at the cost of natural intuition 
for humans.

Webfinger enables one make a de-referencable URI for acct: and mailto: 
schemes. The problem for mailto: is that most apps will invoke an email 

Re. Linked Data scenario [1], the only hold up is the Web browser 
variant of user agent. Put differently, on a mobile platform e.g., iOS5 
you can pull off Linked Data follow-your-nose via an iOS5 specific 
Linked Data using an URI scheme that provides a hook for HTTP (or other 
protocols) based data access.

Using http: scheme URIs for Linked Data is cost-effective and 
unobtrusive in a Web browser dominated Web. That doesn't mean its the 
only way :-)


-- if you click on the @href that anchors the text in the "About:" 
section you'll see what I mean re. mailto: (i.e., email client would be 
invoked) and browser myopia (not accommodating alternative schemes with 
ease) re. URIs .
