  This is supported much more robustly in NT/2000 than in 9x/ME.  If
you are running NT, this is pretty straightforward; you will have two
NICs with separate addresses (on separate subnets), and in fact your
machine can become a router linking the two nets by checking the box
on the "IP Forwarding" tab in the TCP/IP properties.  [This will
allow the kids to connect to your wife's PC.  To connect them to the
Internet, you'll need to be doing NAT somewhere -- perhaps it's a
feature that can be enabled on the cable modem, or perhaps you'll
have to run third-party software on your machine *instead of* NT's
routing capability.  WinGate is perhaps the best-known such product,
although there are half a dozen other decent products on the market.
