Hmmm.  I bet we could generate this (if you dont mind tt800 or its MT 
ilk), in software using some really neat and very powerful (and 
inexpensive) COTS chips.  Dont know if we could hit 0.1 GRPS (gigarand 
per second), but I bet it could come pretty close.

I have been thinking about a USB dongle for the past few months that 
provided random ints at a pretty nice rate.  The chip I have in mind for 
this might be able to be powered off the USB port also (I think, I need 
to see the overall power needs).

Could do a PCI card... would cost more to fabricate and sell.  The $30 
mark might be low.  I'd guess closer to about $100 for that, unless we 
could get significant volumes  ... (economies of scale work wonders for 
component pricing).
