I'm not familiar with sip, but I can easily imagine a http server 
returning some metadata documents for some specific sip: URIs, the same 
way it could for some specific mailto: URI.

The only thing you have to do to make such a server work is to set it up 
so that it responds to requests of the form

GET mailto:abc@example.com HTTP/1.1

or some such. This is allowed by http, it's how proxying works. The 
responses are not authoritative, but they have mime types and may work 
with fragment identifiers.

Regards,   Martin.
