I had a great experience putting something together using an ALIX 6f2 (http://www.pcengines.ch/alix6f2.htm http://www.pcengines.ch/alix6f2.htm) which I bought via a Netgate kit with enclosure (http://store.netgate.com/Network-Computers-C2.aspx http://store.netgate.com/Network-Computers-C2.aspx). Netgate isn't selling that one but is selling other boards which you can put together something similar. The APU line looks really interesting. The cool thing about the ALIX and APU boards is they often support buying things like 3g modem cards which you can use to multi-home your connections with pfSense. You could also create an SMS gateway or similar service.
