There's already been a bit of research into this field (my own PhD
thesis included[ShamelessPlug]). A couple of papers that come to mind
are:
@InProceedings{WebTagger,

}

pages = "1003--1008",
}

I don't think it's quite as simple as that. I'm sure you've already
consisdered this, but one of the biggest problems is in identifying
which content to attempt to attach your buttons to. And then, with
already-framed content, working out how your rating buttons will
relate to the sub-frames (if at all). Further, is any rating shared
among all components from which the page is constructed (e.g.
including the graphics - which are sometimes more important than their
container), or just the container?

I can't offer help in that way, but I can offer a few more references
to folks that have developed extensible proxy servers with aims like
this in mind:
@Article{Strand,
author = "Charles Brooks and Murray S. Mazer and Scott Meeks and Jim
Miller",
title = "{Application-Specific Proxy Servers as {HTTP} Stream
Transducers}",
journal = "World Wide Web Journal",
year = 1995,
volume = "1",
number = "1",
pages = "539--548"
}
@Misc{V6,
author = "Bernard Lang and Fran\c{c}ois Rouaix",
title = "{The {V6} Web Engine}",
URL = "URL:http://pauillac.inria.fr/\%7Erouaix/V6/",
}
I used a (heavily) modified version of the code in sfgate, but that
was mostly because it was in Perl (and therefore hideously expensive
and not particularly useful for anything but some prototype research):
@Article{SFgaate,
author = "Ulrich Pfeifer and Norbert Fuhr and Tung Huynh",
title = "{Searching structured documents with the enhanced
retrieval functionality of {freeWAIS-sf} and
{SFgate}}",
journal = "Computer Networks and {ISDN} Systems",
year = "1995",
volume = "27",
number = "6",
pages = "1027--1036",
}
Another slightly related work is:
@Misc{SIMON,
author = "Mark J. Johnson and E. H. Mamdani",
title = "{Feedback In Internet Resource Discovery Systems:
{SIMON}}",
URL =
"URL:http://web.elec.qmw.ac.uk/simon/irdpaper/ird-paper\_1.html",
year = 1994,
month = nov,
}

I'm not certain whether this is or is not an area in which WREC will
become interested in any way (with apologies if this is just noise).
Proxies certainly sit in an interesting point within the network, and
therefore see a lot of information which is very useful. It's
somewhat possible that they offer the ability to help index more of
the Web than may be possible by the big search engines' robots - but I
think that's another topic...
