I use it at a small B2C shop and about 1 in 1000 customers does use it. It's a custom implementation I once spend a few hours on, so there's nobody taking a cut except the miners. At this adoption rate, I won't invest any more time if it ever breaks. The transaction costs are actually higher now than they are anywhere else, and both PayPal as well as credit cards are faster. Next year, the new EU legislation will open the market pretty wide and I'm expecting (almost-)free, instant transactions to be available Europe-wide (our market). I had actually forgotten all about it until a few weeks ago, when I accidentally started the wallet app, and got quite excited seeing the balance. I got accidentally lucky by speculating in BC for the last three years :)
