Actually, SmartOS (Solaris) has some magic Docker fakery that makes containers run in LX-branded zones. I'm a maintainer of runC (the low-level executor of Docker) and I just merged some code the other day that is working on running runC natively on Solaris. I'm quite excited about that. As for FreeBSD, there was some work in Docker some time ago on getting Docker to work on FreeBSD. I don't think all of the code is there though.
