===== Bid/Ask Federation =====

A distributed database of asks/bids. An ask or bid offer is created, signed, and communicated into a telehash network.

Clients can subscribe to a telehash channel and receive new offer information. Some service perhaps to catch them up on old information. 

Another service to take query requests for those who dont want to run a client that receives offer information.

basic distinction: are the offer records(DNS) distributed or the search requests(gnutella)? far less traffic in distributing the offer records than distributing the search queries. 


===== Escrow Service (ES) =====
