You can build a proxy into IE that modifies simple headers easily (actually
you can, I think, do it simply via the registry, and 5 lines of script to
provide the registry changing...), coupling an RDF parser into is certainly
non-trivial, you also have the problem of educating users to author
appropriate vocabularies, or develop a suitable editor.  CC/PP is massively
over-engineered for the above, doesn't work simply with web caches (unlike
Nick's x-accessibility header)   A simple view header which describes what
resource you want from the server, is very different to describing to the
server what you can deal with, and leaving it up to the server to decide
what to give.
