Google wants all wireless spectrum auctions to be "open" in the following ways:

a) Open Applications
b) Open Devices
c) Open Services
d) Open Networks (access)

They are committing $4.6B to the auction if these standards are upheld.

Quoted: Eric Schmidt today sent a letter to FCC Chairman Kevin Martin, saying that, should the FCC adopt all four license conditions requested above, Google intends to commit at least $4.6 billion to bidding for spectrum in the upcoming 700 Mhz auction.

Kompolt is the most well known seller of unique experiences that benefit charites. This page is a listing of their current auctions.

Looking for a one-of-a-kind experience - some not available from any other source? Look at the Charity auction "experiences" for sale on eBay. Everything from VIP concert tickets to lunches with celebrities.

And they all benefit a sponsoring charity!

Each day, Jellyfish holds a reverse auction (price drops, until enough people bid on it to deplete the inventory). Kind of like "shopping chicken". Looks pretty fun.
