Looking at ‘man tc-flower’, it does sound like an option. I suppose that one instance of Cake per member will be somewhat similar computationally to one instance for multiple members. There will be additional memory used, and additional processing for the filters. This would also probably only be practical if members only use one access point, which I do think is typical. A few dozen filters and Cake instances might be ok, but I’m not sure about 800. :) We’ll see what we come up with. Thanks…
