3rd party transaction fee business

[TTBit]

Has a 3rd party transaction fee business been discussed?

A business keeps a public database of transactions. If one of the tx are included in a block, a bounty is paid to the newly generated coin address. Miners can choose to look at this database or ignore it, but they will get the bounty regardless.

* The 3rd party now has an incentive to include as many tx as possible, and could pay less for small blocks, more for larger ones - enough to offset the cost of not including them (not sure if the economics of that work out).
* could negotiate with MtGox / BitPay for bulk rates on transactions, customers wouldn't have to worry about fees sending or receiving.
