I think you pretty much nailed it, Mr. D. I am, however, fiddling with
Debian and Debian Edu for the stand-alones and servers. Some people end
up really liking DSL on the older computers, but these are the more
elite. I like the Puppy.
We've pretty much always taken this approach though the increasing
number of P4s/Athlons/Opterons is changing it:
399 mhz and slower - Thin Client/puppy/dsl
400 mhz to 599 mhz - firewall/content filter/puppy/xubuntu
600 mhz to 1 ghz - stand alones of any flavor
1 ghz and up - Thin client servers or workstations with expected
video/graphical editing/processing.
Clonezilla is master of the universe in this environment, and I don't
know how I lived so long without it.
Try not to limit this to a one time or an occasional event. It needs to
be a way of life until everyone who wants or needs a computer can get
one. I realize that this is flying perilously close to the emerging,
inexpensive, energy-efficient PCs and PDAs. For many, though, there is
still a monumental difference between $50 and $200.
Rock on, Daddy-O.
