This is a good Offer HN opportunity. (I know, I know, that's so last week.) You could tell people that they can email you with the max they'll pay, and you'll go and bid for whoever has the highest max. And I guess you should say that you'll definitely bid at least the second highest max you heard, so that we don't end up shorting Bing. (eg. Someone gives you a max of $5k. Someone else gives you a max of $4k. But the highest bid from anyone at the auction is $2k. So you bid $2500 on behalf of the $5k person and win it for them. If the $4k person and the $5k person had gotten different proxies, Bing would have gotten >$4k, but because there was a sort of pre-auction, they only got $2500. By saying that you'll definitely bid as high as the second-highest emailer, you avoid that problem.) Just make sure you vet the person pretty well so you know they'll actually pay. I'd do this myself, but I'll be on a plane back from Rubyconf that evening.
