Google Spider on the Fly

Google has now enabled us to create “custom search engines on the fly.” You tell Google the URL of the page you want the ability to search — e.g. your own blog main page — embed the resuting code in your page, and then when a search term is entered into the Google search box on your page results will appear from all of the sites linked from your page.

This would, in effect, create a search engine out of all of the sites on your blogroll, which, if your blog focus was sufficiently tight and your blogroll reflected that, might make some sense.
