Unless blockchain.info is involved

Indeed. We all here accept payments as soon as they are on the blockhain without waiting for confirmations. Takes no more than a few seconds in the absolute majority of cases. Only blockchain.info webwalletstuff is a problem as it takes unneccessarily longer.

We will keep on doing so untill we suffer the first double-spend attack, which I expect some time soon actually, carried out by some nerds as proof of concept who will come back after an hour and smile and pay their bill anyway

Does anyone know where I can get the window stickers for "Bitcoin taken here"? See below:

I'm trying to create packs for retailers all round the world and want to do a push to all the small shops in Brighton, UK:

https://bitcointalksearch.org/topic/introductory-packs-for-retailers-about-bitcoin-and-litecoin-188918

Bitmit seems like a good start:

https://www.bitmit.net/de/item/29675-10-bitcoin-sticker-9-8-x-9-8-cm and https://www.bitmit.net/de/item/20068-bitcoin-accepted-here-vinyl-window-cling-sticker are the most popular ones.

Thanks! I've just signed up and bought 100 stickers to give out.

What tablet application/website was ROOM77 using to accept customer payments in the Guardian video? I'm trying to write up an info sheet of methods to take customer payemtn so a list of different methods of how to do this would be useful:

Despite what you may read about the forum, unconfirmed transactions work plenty well enough for this sort of thing.

What if you send a 0-fee TX that doesn't exceed the priority threshold, so it will sit unconfirmed for days, but then you are able to double spend it back to another address of yours with a fee when you get back home?

Of course there are risks.

But how often would this happen?

1. If you do a double spend in a shop or a bar, you will never shop there again or drink a beer there again
2. We are not talking about values of 1000nds of $ here, but a normal Bill at a bar or shop
3. If that's you reasoning as a shop owner, you should also not accept Credit Cards, because the person could always do a charge back later or the Credit doesn't have any backing
4. The normal user isn't even able to do a double spend and it will get less and less the more Bitcoin goes mainstream, but everyone can do a CC charge back or pay without having enough backing on his account.

In addition there is always the "risk" that your transaction actually confirms.

If your transaction doesn't contain the minimum fee, it will not be relayed to the shop owner neither.

Didn't see if someone already posted this in the thread, but here's a link to the video about bitcoin in Kreuzberg:

I'll be over for a long weekend this summer--I'll try to make that bitcoin night.

Exactly. Trying to make a double spend in bar or a brick and mortar Shop is by far riskier than to just grab you item and make a run for it.

do transactions go through fast enough to make this viable....?

Again someone confusing transactions with confirmations?

A transaction takes usually 1-2 Seconds.

Yes, this go trough fast enough.
