(I'm assuming that a signed payment\nrequest is not always going to be all that useful in the case of\nprivate individuals, even assuming the payee is willing to sign up for\none.)\n\n\u003e Likewise, I could attach a payment request to an email and send it to you,\n\u003e and now you can pay me whenever you want forever.\n\nThat certainly sounds like a plausible use case.  You do still have\nthe problem that e-mail is an insecure channel, but it's no worse than\nexchanging Bitcoin addreses over e-mail as things stand at the\nmoment.\n\nroy"}
