This only reduces to pairwise interactions if you trust the auctioneer to inform all parties, impartially and in a timely fashion, of every bid. In addition to being an interesting trust and non-repudiation issue (and getting into reliable messaging as well!) such a pairwise solution really doesn't scale very well. A multicast approach models the human notion of auction much better, and this pushes it into the multiparty zone..... I'd be interested in comments from folks who've been involved in auction and other negotiation work; David Levine of IBM, for instance. Geoff
