If you want hardware to run this on, I really like the PCEngines APU (http://www.pcengines.ch/apu1d4.htm), which is surprisingly powerful (dual AMD64 cores, 4GB RAM, multiple miniPCIe ports), and inexpensive given the capabilities.
Improvements over the first version: quad core, Intel Gigabit NICS, new CPU supports AES-NI and AVX (AMD-V), ECC memory, and a USB 3.0 bus. Still some issues being ironed out, but will make excellent router hardware. Note that WiFi is a relative weakness on BSD, and you'll need to carefully choose a chipset to support hostap mode. The Atheros abgn cards are generally the best.
(Lack of Intel ethernet ruled out the APU out for me)
Also - How did you know about this? I can't find that page by browsing their site and I didn't even know this existed!
I'm also looking for a good wireless access point. Any suggestions?
You should be able to do a killall dhcp if you don't want to use it.
