Layman's help for oil rig disaster?

I’ve had this thought before with other (nature) disasters, and now again with the latest oil rig disaster in the Gulf of Mexico.
I heard the plan from the BP company to put a dome over the principal leak tonight.
My thought is this: Would it be an idea to, whenever a major disaster takes place, launch a website where people from all over the world can put ideas to help recover/repair/ the troubles coming from those disasters?
Of course there is a lot of expertise in companies and/or governments, but aren’t there maybe also experts under the laymen of the world?
