Hmm... I'm not sure of how a Dutch auction for multiple goods would work. It would confuse some bidders too (heck, I've been getting PM's on how basic auctions work)
Easier than you'd think. You have a countdown clock counting down the price from high to low, say 1 btc per hour. As soon as someone accepts a price for a number of items, those items are sold at that price.
It's a very quick auction method, and has the advantage that it can still sell some items before a reserve is reached. It doesn't matter if people know the price range beforehand since they don't know how others will bid. Since people *really* don't want to be left out, they'll probably bid earlier rather than later (when the price is lower but the probability of missing out is higher).
This method removes the end of auction sniping that occurs in English auctions. You wait until the price hits something you can afford and then you post once and you're done, or you miss out. No more having to check the thread regularly
after you bid and repost every time someone makes a new bid.
