Let's mashup this flu

... when typing in a zip code Google offers a new feature displaying where flu vaccins are available. Only one major hickup: the efficiency of this tool is totally linked to the availability of the data. Reserves need to be reported. And I imagine reserves need to be monitored as well, almost in real time, to avoid rushes on health centers that are supposed to have vaccins according to Google but ran out some time ago. Still: a cool way of mashing up data. With thanks to the guys from Smartplanet. Oh, and only in the US, I imagine?
