hi joepie.
if noone is willing or able to do the above (i probably don't have time), then perhaps i can buy the domain off you, to strengthen my brand.
I am not looking to sell the domain.
My experience of donation based projects it that they are fine for sidelines and vanity/fun experiments. As soon as you start playing with other people's money (or bitcoins) you really NEED to charge something for everyone's sake. The project must self finance, be attractive enough to draw investment when needed, be able to afford to fix security holes quickly, and strangely by charging you give a value to the service of looking after the processing of MONEY.
As long as the price is not excessive, but is enough for trust to exist, I don't think there would be a problem.
My experience of donation based projects is that they are easily funded by donations alone, and that I literally live off donations without any job or other income stream next to it that is not completely voluntary for people to contribute to. I don't see why that would have to be different for a payment gateway.
Quite often have people told me that certain things were not going to work ("how can you possibly live without having a job or social security payments?!") yet everytime things go fine. Possibilities are only limited if you think they are limited. "Doomsaying" won't ever get any work done.
We would be interested in setting this up. The only problem we have is the ability to charge. We could offer a basic e-wallet/merchant services for free and then additional charges. If you would be interested or want to discuss more feel free to contact.
The conditions as they are in the OP stand and will not change, regardless of offer.
I've setup
https://coinb.in which I think matches your specification.
Let me know what you think.
It does look very nice and I think it's a good service and pretty much matches my conditions, however you don't appear to be a very well-known person in the community which is an issue, plus you already have a very good domain (imo).
I would like to remind people once more that the conditions as above won't change, and that I'm active here out of ideological reasons, not because I want to make money. If you want to try and offer money to get around the conditions, don't bother - I am not interested in commercial dealings. I'd want this domain to end up with someone who isn't in it for the money, but because he believes in the concept. If noone is found, then I will just keep the domain name and set it up myself along those specifications at a later point in time when I have the time for it.
