in thread Fuzzy matching to user's tastes?

If you are worried about only one person getting any specific item, look at who bids instead. Then use some kind of classifier on the bidding patterns to find each user's k nearest neighbors for some k. When a user bids on something, message his neighbors (unless they've been messaged already).
