<tinfoil hat>Be aware that the opkg tool used by *WRT will happily download unsigned binaries over HTTP. Fortunately, the offical repositories for OpenWRT can be accessed via HTTP. Unfortunately, their documentation uses "http://" all over the place instead of "https://" .</tinfoil hat>
It is good to keep this in mind. For now, I have only plugged the thing in to a power bank, and transferred files to it via scp, just to see if things would work. Next on the list is to put together a customized OpenWrt build (one that actually has everything in place for bridging) and will remember this when preparing the config file for opkg.
