You probably should explain in greater detail how you'd like to use
it. websitary[1] does something like this according to its blurb. It's
rather lo-fi though and was meant to be little more than a websec
replacement for personal use.

You can use the Mechanize gem to fetch one or more pages from a site and
then compare it to a saved version to detect changes. If the page has a
time/date stamp, it won't match exactly so you'll probably want to
figure out some way to monitor the parts of the page that matter to you.
Regular expressions will be your friend here.

HTH,
