Yeah I actually hesitated to even suggest it :) Though once you've done 
it its not _that_ bad. We do this in our autotests framework to simulate 
networks, and run multiple instances of IWD. You may be able to do it 
with a container as well.

And with two WiFi connections and 802.11r Fast Transition if possible, I hope to get network interruptions close to zero. Redundancy itself is done on application level.
So this very same thing is being added in WiFi 7, called Multi-Link 
Operation (MLO). It doesn't help you now as IWD doesn't have any logic 
for it but just putting it out there (and maybe AP support is also 
needed). They've been working on this feature in the kernel for quite 
some time now.
