Hmm.. part of the design has to be a fat enough wire leading
to my home.  A quick calculation 

	| 1 - boomer:david --> bc
	scale=3
	1000000000/24
	41666666.666
	./60
	694444.444
	./60
	11574.074

Says the wire will need to handle over 100Kbits-per-second all
day long.  Hmm.. up til now my TB+ seemed pretty capable of 
the job.  Sigh.. if only I were Rob Pike AT&T would be willing
to pay for T1 lines to the house, ohwell. ;-)

ISDN doesn't cut it -- it's only 56Kbaud.

But then it will require 6 doublings of traffic.  In the
past each doubling has required 18 months, up until the
a.s.pictures nonsense hit us.  Reaching 1G/day should then
take somewhere between 3 and 10 years, depending on whether
the volume curve is really increasing.
