That's true, but the port work described in this post is older (predating the fork of LEDE and OpenWRT), and the latest work regarding these zsun devices are more recent (but they haven't been upstreamed into LEDE, and so haven't been merged back into OpenWRT, either).
So the state of the art for these devices is a couple of months old LEDE builds.

This seems to be a somewhat rare feature... I might get one just to try this.
Does anyone know of other cards that support something like this? Is there a difference between being able to associate with multiple APs and being able to host multiple APs (or some combination of both)?
I've been trying to do this for a while, OpenWRT runs but the performance is sub-optimal, maybe it's just me or my impatience (or I got a flaky device) but it freezes a lot.
You might have a flaky device and/or configuration. Some chipsets and devices aren't as stable, but OpenWrt usually maintains a good compatibility list.
It seems like a very good alternative hardware for the same purposes as USB Armory, for a fraction of the price.
I wonder how soon a nice security-oriented package set will emerge. I suppose the USB interface should work as a USB-connected NIC, offering https / ssh / u2f access to the host on the card.

Edit also, there was picture frames at one point with bluetooth that ran linux that were hacked, I made a video years ago, funny to look back on
