Unfortunately, for some of the really specialized refernce works, 20,000
sales is an impossible dream. For our disk of New Hampshire legal stuff it
would be 100% market penetration–not only every lawyer in New Hampshire
but also every Law School in the US and most of the giant New York and
Boston law firms as well. And then we _might_ hit 20,000.
Wherefore we have to price to get our development money back on a
few hundred sales.
