Bid for fix! (read: Pay per feature)!

Some days ago I discovered Osmand for offline browsing of vector maps and navigation (nice tool indeed, though with a pretty different target and purpose from Orux).
I have seen that they use this site to get funded: http://www.bidforfix.com/p/osmand.net/ .
It's bid-for-fix, and I find it AWESOME. Basically, people that want a feature do tip with paypal a certain amount. The developer chooses how that amount should be for that feature.
No money is credited to the bidder until the feature is released, tested, and approved by the bidders themselves. If so, the developer gets his money.

Isn't this BEAUTIFUL?

I would really love to see Oruxmaps there.

What's your opinion, Orux and guys?

Cheers!
