Multimedia streams, routers. If I want to secure a near-future 10 GBit Ethernet stream with a symmetric cypher for the duration of a few years (periodic rekeying from a RNG might help?) I need both lots of internal state (the PRNG can't help leaking information about its state in the cypher stream, though the rate of leakage is the function of smarts of the attacker) and a high data rate. > In any case, if someone wants Gbits per second of random numbers, > it'll cost 'em, as it should.

Maybe, but it's neat trying to see how the constraints of 2d and 3d layout of cells, signal TOF and fanout issues influence PRNG design if lots of state bits and a high data rate are involved. It is not very useful right now, agreed.
