I know several people who have used large quantities of random numbers and could definitely have used something like this as they were running out. In case anyone wants to know what running out means, it means looping around and starting the list over. If you have not used the random number generator in most PCs and Languages today, you may not realise that they are really pseudo random in that they are generated using a formula on a seed number to get a new number which it returns as the random result and then uses the new number as a seed for the next. This produces a very long string of numbers that to all intents and purposes is random... unless you use so many of them that the algorithm starts back over on the list of numbers. My friend was a PhD candidate and was seeing patterns in her data that just could not be explained, she finally tracked it down to the random number generator and the fact that she was using orders of magnitude more numbers than the algorithm could produce. She ended up buying a very large set of random numbers (who would have thought that was a product) so it is nice to see this type of setup where you can get random numbers generated simply and easily. She probably would have still purchased the large block of random numbers as she was using them much faster than the Key here would generate them so it was better for her to purchase a large block than to have to wait for the numbers to be generated.<br>
