Ok, set up your own router and use the firewall to govern what can talk 
where. You can use a triple-homed machine, and two subnets, or a 
dual-homed one and select by IP address - you'll to think about (DHCP) 
address allocation as well as firewalling and routing.

One of your box's interfaces connects to the ISP's box and only that, 
your network(s) are spread across the others.

I did it once (FreeBSD box), it was fun but it really wasn't worth the 
extra hassle. As a side benefit, you can monitor network traffic more 
easily though.
