The use of this? Well... none, because communication via the Internet is either based on encryption using pseudo-random numbers...
Er, no. There's nothing about the Internet's most common cryptographic algorithms (RSA, IDEA, DES, 3DES, and such) that makes it necessary to use pseudo-random numbers. It's just that, without a source of true randomness such as HotBits, pseudo-random is as good as you can get.
