Thanks Tim.  Yes, it is hard to make any money off of any 
core technology in the computer business.  The hardware are 
toasters and the software are bread.  OTOH, folks still pay 
a stable price for well-made sandwiches, so in the content 
business, (eg, the stuff in the cells), we have to find 
ways to let them "have it their way".  Analysis is still 
a pretty good mustard.
Thanks to everyone who sent me URLs today. I very much appreciate 
it.  The reading has been most interesting.
