No, its an InterWeb scale identifier that's verifiable using the WebID 
verification (authentication) protocol.

<http://twitter.com/kidehen#this> is a URI associated with an object 
accessible from Twitter's Web accessible data space.

The aforementioned URI is de-referencable. It resolves to a structured 
representation it the URI referents description.

No.

FOAF is an option re. vocabulary that defines the structure of a profile 
oriented data objects. You can use a FOAF based object craft a data 
structure that provides relations that ultimately connect a WebID to a 
Public Key or even an X.509 certificate hash i.e., Fingerprint .

Failing to separate concept, data representation syntax, and data 
serialization formats is still making matters a little confusing re. 
Linked Data.

No, it is about verifiable identity via identifiers via exploitation of:

1. existing InterWeb infrastucture
2. trust logic and structured data representation.

How can I create a URI in other people's namespaces associated with 
their data spaces? I am a URI to identify a chunk of network accessible 
data in a manner that's distinct from the representation of said chunk 
of data.

Of course note, a chunk of data (i.e., a data object) is endowed with 
the following fundamental characteristics:

1. an Identifier (a URI)
2. Representation (a graph pictorial in EAV/SPO triple form)
3. an Access Address (typically a function specific identifier e.g., a URL).

I hope this clears up matters for you :-)
