I think you missed the point ! One does not ask the question "How does
one get a 32.768KHz signal from our 10MHz reference ?" and not expect
it to cost both in terms of money and effort. There was no statement
of doing it cheap, re-read the original Email.

You're missing the point. The application is to drive a common,
available consumer clock. Simple and cheap. It can be done with a
single $1 PIC. You could spend $20 or $100 and not get better
for the application. If you can describe a way of doing it for
