if tosaki isn't answering at all, he and his service deserve to get some heat. it's a free market and as you can see in my sig i still consider his the best option but i'm happy to jump on any competition that raises above his currently poor reputation. if he speaks up and deals with his customers, he deserves all the fame for his great service. if he disappears leaving the server to rot, i hope for competition.

With a good escrow service, bitmit is not needed as much. You could, hypothetically speaking, conduct auctions or sales, on a more popular web based forum, for example. *cough*
