I know you can click on "Bid History" or is it "Bids". That will tell you what each bidder has bid. However, the bid totals (amounts), if I understand it, is blocked until the auction closes. Checking it DURING the auction you can see the identities of all the bidders but not their bids. That is unless the bidders are kept annonomous or private.

Also I found it interesting as was mentioned before in this thread, how a bidder can, incrementally, bid until they see an odd change in prices. Ie. if they see it go from $8.50 to $9 to $9.50... then hits a bid of $10.26 they would know that they have hit the top end of your bid. They can place one more bid to beat you or stop and try and stick it to you.
