Thanks for your concern, it makes sense after all!
I didn't know that other developers were coming out with an exchange, but seeing the disarray in the buy/sell subforums, I decided to pitch in.
The server's written in Node.js, and is doing quite well. I'd be willing to set you have a look at the code if you'd like.
I'm /r/Silfax on reddit, moderator of /r/Jobs4Bitcoins, and pretty well known over there, as well as coder for a couple big group buys.
All that said, the exchange is still in Beta, and might have some security issue I've overlooked, but I'm doing my best to please my customers.
