I'm not sure I fully understand the challange, anyway this is what I have in mind:
Auction server that expose both PUB and ROUTER. Bidders connect to both. Bidder subscribe to relevant auction. When bidder want to mske a bid it sending message to the router which process the bid and publish it. What am I missing?
