Thanks for the feedback on this folks.  Carr and James hit on what I need to 
know.  Here in SCal Verizon >just< started offering the Westel VersaLink 
327W modem that is a cable router, hardware firewall, and wireless router as 
well as a DSL modem.  So the hardware setup is all set.

From what James wrote, I should be able to get all of these PCs working by 
just setting setting up basic networking as I've done in the past, and 
assigning each an individual IP address.

A while back in another forum, I was told that to get a home network going 
properly (though I found it not to be necessary for WXP to W98 on my desktop 
to Lib), I'd need to assign fixed IP addresses to each system.  And it was 
recommended to use 192.168.1.101 for the first machine, 192.168.1.102 for 
the second, 192.168.1.103 for the third etc., and 255.255.255.0 for the 
SubNet mask on each.

Could it all be that simple?  Or like most things related to computers, are 
there many ways to go about this?

If you have "basic networking" setup already, it is likely each of your
systems already has an IP address.
Typically, when you get broadband for a home, you only get one externally
visible IP address.  If you want multiple machines within the home to share
the broadband connection, you need a router  that implements NAT, or 
Network
Address Translation.  This means that the router uses the externally 
visible
IP address and multiplexes it to the multiple machines inside, each of 
which
get their own IP address that is *not* externally visible.

These addresses are typically handed out to the internal machines
automatically from a DHCP (dynamic host configuration protocol)  server,
typically running in the router itself.  All you have to do is configure 
the
clients to "get IP address automatically" or some such and it will all
happen automatically.

I suspect that if you sign up for the verizon service that includes 
"running
multiple computers" that the box they give you will be a router that does
the NAT and the DHCP.

Hope that helps,
