At home, my Linux box is now wired to 21 houses on a WAN and its the sole DNS for the 37 machines wired into it. I have been experimenting with WAN and LAN setups and talked afew of my neighbors into this setup. 3 have satellite and 2 have 1/2Ts. With some help (I still dont understand it all but learning) we bonded the 5 sources into 1 big pipe that we all share. The 3 satellite systems use the Linux box as a network Modem and the 1/2Ts use it as a router for the other systems. This being done on a P3 650 box with 768mb main ram and a 20gig HD...you should see that box chug!
