I'm based in Germany and have been using FreeBSD since 2.0.5. I've dabbled in FreeBSD development mostly on the sidelines (some ports, some work on NETATALK protocol support).
FreeBSD on Embedded Platforms
I'm currently helping to finish work to have FreeBSD run on various Atheros-based wireless routers. StefanBethke/EtherSwitch has some thought on how to implement an ethernet switch configuration framework.
