I'm not sure how well this would work. Sure it would provide honest historical pricing, but those who wait for publication confirmation may be at a disadvantage -- to get the best deal possible Bob would connect to as many nodes as he could, examine the stream of unconfirmed asks coming in and sign the best ones before someone else does. The network would gravitate towards an O(n^2) fully connected network, because being fully connected means one is fully aware of all unconfirmed asks at any moment so one can make the best judgement and buy before someone else does.
The seller needs a guarantee that all bidders can act on the ask transaction simultaneously. Maybe the partial ask transaction could be time-locked with a network propagation delay, there would be multiple bidder responses and the winner is chosen by lottery (and fee priority) by the bitcoin/alt-coin miner who confirms the atomic transaction in their block. That would eliminate the advantage to being fully connected as it would no longer matter that one can act first, so you have a more sane network.
