Cool. I think that we should look seriously at generating annotea annotations
for pages as an option. As I understand it, for a given page we would do a
POST to an Annotea server of the EARL that we have.

Ther is more information at the Annotea protocols page
http://www.w3.org/2001/Annotea/User/Protocol but my rough summary is you post
something like the following:

POST /annot HTTP/1.1
Host: annotea.example.org
Content-Type: application/xml
Content-Length: 1082

   </earl>

(Should check that with an annotea wizard)

You can then query the server for annotations and see what other people said,
or compare, or ... (all it needs is some user interface wizardry <grin/>)
