Or a service like Netflix could include local network movies (on networked hard drives, or DVR's) in their search results, and play them from the same interface.
Here's my concern - if you say "a service like <x>" might want to search for something, that is better described as "a random website".  That may be something the user wants, alternatively it could be something evil.  It could also be something evil embedded in an ad on the site a user "trusts".

My concern here is that as a web spec this essentially acts as a way for arbitrary web content from any source to perform a network scan of your local machine and get data about your internal network topology and services from inside your firewall.  That's a really scary concept to me.
