You can also use this web-service with an URL query-string of the form:

?url1=http-url-to-doc-1&url2=http-url-to-doc-2

which makes it possible to send around links to diffs between document versions withouth actually generating the diff yourself, as long as the two document versions are available by http.

Example (yes, it is long - no way to get around that... - but you could use tinyurl.com to get a short alias to one of these):

?
  url1=http://tools.ietf.org/id/draft-ietf-atompub-format-10.txt
  &url2=http://tools.ietf.org/id/draft-ietf-atompub-format-11.txt
