@stan,
Actually your idea is great! But, why it's only for "Houston"?
Why we can't use BitShares donations process to world wide natural disasters and to the people who wish to eat atleast once a day?
This is not something aggressive, like you all build BitShares platform, shall we all build a platform which can be used to help all man kind, specially people who need our help!
I was thinking about this few times but eventually failed! But if people like you... could initiate something like a global project I think it might help every person on this earth and as you said before, BitShares the next BitCoin will make millions or billions of dollar is next 2-3 years of time as well!

Respect the way you think! And I think we all must participate such events!

Cheers~
