I'm also a fan of doing one thing well.

But, in all my thinking about RNGs over the last decade it has
strategically ended up in this point:  it is too small a direct market
to make it happen.  The number of people who will buy an RNG is too small.

Indeed if you wrap together the number of people who will buy a great
RNG with those who'll buy a crappy RNG ... it's still too small.

Yet, everyone *everyone needs a great RNG* and nobody will get one.
This is a case of a best-gets-you-nothing market.

So, I speculate that the way to make this happen in the large is to add
the RNG to another device.  Indeed, make RNG designs as open .. so
manufacturers can start to add them in ... flashy adverts "and you get
an RNG for free!!!  why wouldn't you buy???"

It's market-strategic thinking.

And, if you're going to do that ... who else will buy an RNG?  Close
correlation with those who will buy a USB firewall.  I'd reckon.
