I am going to lower the buy now price to 15 BTC. I think it's fair to say that there has been little interest so far from this community to run an exchange.
In addition, if the auction has not received an official bid before the 22nth, I will prematurely close down the auction and consequently take measures to shut down the service gracefully. After that the codebase is still for sale by PM, however non-exclusively and with no users/branding/marketing/servers.
