When we sold Kiko on eBay, the site was at the minimum bid (50k) until the last morning, when it jumped to 75k. In the last 30 minutes it jumped to 256.1k. Don't worry if people don't start bidding immediately, but I suggest you go out and try to drum up some tech news about it (TC, ReadWriteWeb, etc). You'd be surprised how much getting the word out can add to the value of an auction of a one-of-a-kind item like this.
