Organisations often need to rapidly communicate to end users via the web. If a flight crashes, product is recalled, emergency at the comapany etc….people hit the web first. An ideal function would be the ability to flash update meta desc and title and have search engines flush their cached title and snippet. This means even if the corporate site goes offline under traffic load the serp will display a useful update within the snippet and title. The URL could even be redirected or shown in an emergency sitelink. Thus an airline that has lost a flight would go from a serp entry of:
TITLE: Acme – cheap flights to new York and Chicago.
SNIPPET: Air Acme is the northwests leading low cost airline with superior legroom and free seat reservations
URL: www.airacme.com
TO:
TITLE: Air Acme: Flight 345 NYC -ORD Crash. All other flights safe but grounded.
SNIPPET: Emergency hotline 1 800 000 1234 Air acme. 1 800 367 4566 JFK. 1 800 222 5678 ORD.

This ability would be used infrequently but allow search engines to play a better role in assisting organisations and the effected people in crisis. A ping submit used in conjunction with the urgent update tag / flag on the organisation site as the first thing to fall in most crisis situation is often the website. This was what we saw on our web monitors in 9/11 and many times since, leaving families scrabbling for information.
Currently you would have to use PPC to get this turnaround time.
