Paul, how do the semantics of the two things you described differ?
The google results page is exactly what happens when  "accepts and
processes data".

The web information space is enabled by the clinet never knowing, caring
or specifying "what the server does", only defining in some way what
information it wants.
Whenever the information retreival function is repeatable and has no side
effects,
then it is useful to reuse the input as a URI.

The only problem is when the URI gets really very long indeed.
