Jim,

    Take look at DD-WRT (http://www.dd-wrt.com). It is a mini-distro 
designed to replace the firmware on many models of Linksys, Buffalo and 
Netgear SOHO router/gateway products. They also have ported to a few 
board level single-board computers that are a bit more robust. Most are 
based on the Broadcom embedded processors. It has many features 
including samba and nfs, dhcp, tftp, ftp, iptables, ssh, etc. By 
underclocking the processor you can get it down to very low power usage. 
With a router board that has a compact flash port (CF disk) you could 
get 8GB of fast local storage, equal to a lower end laptop drive.

Here is a link to a board level product that works well with dd-wrt and 
has a CF slot. http://www.routerboard.com/rb500.html
