Yes, it probably is a path that one would take while
designing hidden services.  However, I think that it
is a different fork of the main thought process that
leads to a different (not better, but better for 
somethings) use case.

Agreed, a single path encoding is a weak point, but this
may be acceptable in some cases.  Also, other mechanisms
could eventually be built on top of this mechanism to 
replicate a document to several places and provide 
several obfuscated URLs to the same content.  This 
suddenly makes this content much less vulnerable to 
single points of failure than a hidden service, 
hopefully. :)

I agree that it is optimized for this, but I hardly
think that you could make the claim that static content
has no place in tor, could you?  Anti censorship is not
just about dynamic content, visit onion land for plenty
of static content examples.

...not to mention that dynamic systems could potentially
be layered on top of this static mechanism, again 
hopefully. :)

Relevance?  How does this enable bulk files transfers
anymore than what tor provides today?  I fail to see
the connection, but perhaps I a missing something.
