JBidwatcher

A Java-based application allowing you to monitor auctions you're not part of, submit bids, snipe (bid at the last moment), and otherwise track your auction-site experience.

It includes adult-auction management, MANY currencies (pound, dollar (US, Canada, Australian, and New Taiwanese) and euro, presently), drag-and-drop of auction URLs, an original, unique and powerful 'multisniping' feature, a relatively nice UI, and is known to work cleanly under Linux, Windows, Solaris, and MacOSX from the same binary.
