You mean, they had the best marketing :)  if they had a product, you 
would have had it.

It's a recurring theme -- there doesn't seem to be enough market demand 
for Hardware RNGs.

I once toyed with the idea of creating an open source hardware design 
for a USB interface.  Then, seed the market by buying a few thou.  And 
finally, encourage random USB parts manufacturers to just throw it on to 
their chip.

The thing is, the real estate required for a hardware RNG is fairly 
minimal, and USB devices can be promiscuous, offering multiple 
interfaces for little effort.  So why not come up with a USB memory 
stick that also advertises a random file as a separate device?

Just a pipe dream, needs a hardware geek to push it.
