Get the software to send the URL to Google automatically upon deletion?

Easy. Set a bot listening on rc and sending the retrieve-url for each deletion of a page with more than X hours (thus probably cached)... until google starts asking you for a captcha.
Sending Google the URL should only be done if there's a problem with Google cache (ie. complaints, when deleting you foresee problems...) and these small cases can be manually sent by the sysop.
