Right, that is a good explanation why no consumer HW with this feature

Hmm... Yes antenna placement is important and difficult, but I know
setups where this works quite well. E.g. using RouterStation Pro with 3
MiniPCI cards (ath5k/ath9k).

For one part I'm trying to find alternatives to that RouterStationPro
board which is EOL.
But in the current case I actually want to have one or more radios in
monitor mode (running "horst", switching thru channels) and another one
for connectivity (mesh). In this case the interference problems you
mention don't exist, but I admit that this is not a very usual
