Yeah, that was the way my thoughts were going. OTOH, you wouldn't need to generate the random data yourself, you'd just need enough of it to exist and define it as your dice throws. There must be thousands of computers spending lots of time generating pseudo-random numbers, so you just need some canonical arranging of their streams into result sets of 20 dice, and you could in principle find any of the results, and one of them will have come up 43562522633613246253 a.s. :)

"been sent money by the tax office of a country of which I'm not a citizen and indeed have never even visited" ?

They used PuTTY internally and decided they wanted to send us a load of thank-you money. The slight catch was, being a government agency they weren't allowed to make dodgy donations to people via PayPal, so instead they asked us to send them an invoice.

It's quite difficult writing an invoice for doing no (specific) work, when you're reasonably sure it will be read by part of a general accounts-payable department who isn't the guy who fully understands what the money's for. I ended up writing on the invoice "PuTTY development, as discussed in <message-id>" and printing my contact's name prominently, in the hope that the accounts department would either just accept it or check with him for approval. I don't know which one happened, but we did get the money :-)

Aww. That quite restores my faith in taxmen :) It really is nice.

And I wanted to check if it was just money from a tax office, or if it was in some way tax money.
