Re: Nor a good solution
"You can't send cash remotely other than by courier or mail service."
Sure you can. I've done it. There are several methods available, but prepaid debit cards are the easiest (you can load the card from anywhere, without having to physically possess the card).
That's not entirely anonymous, as the card company knows when and where you withdraw the money, but you can, at least, load the card anonymously.
