for a simple GeoJSON-emitting projection web service. Not that
useful at this point (it only takes in points), but it demonstrates
some possibilities...

There is no direct support in OpenLayers for this -- this is in the
Pleiades development that Sean Gilles has worked on. (I'd never seen
that page before today.)
The search results in
http://developers.metacarta.com/gallery/item/cambridgema.gov/geosearch.html
are delivered using JSON, as an example of something that does use JSON
for transport of geoinformation -- but this is also not built into
OpenLayers, but part of a MetaCarta specific extension. You can browse
that format, and a number of our other formats for delivering geographic
content via JSON, at http://developers.metacarta.com/explorer/ . These
include gazetteer lookups, query parsing, and geotagging.
