This one is just a bit esoteric, but there is a solution. It's called link aggregation, or a lagg interface. What this means is that you combine two interfaces into one virtual interface, either for load balancing or failover if your primary interface becomes unavailable. You'd want the latter. It's covered in section 34.9 of the FreeBSD handbook under advanced networking. If you scroll down they give an example of setting this up for using a wired connection as your primary and wireless as the failover.

You should be able to move between different wireless networks using wpa_supplicant. Not sure how that would fit into the scheme I mentioned earlier, because the docs don't mention it specifically.
