I bid $400 :P Thing is, this is still nowhere near what the OP wants to hear, but we haven't been given any real data yet so it's like sticking a flag in quicksand.
HN is likely one of the worst places to try and sell something like this. We all believe we can rewrite 80% of something like this in a couple of weekends, given sufficient caffeine.
The $500 bid is based on the likelihood that if you find a buyer on HN, some tech bloggers will likely pick up the story, and the PR value itself might be worth it.
