The "sharing a certain amount of bandwidth" idea from the article is way more difficult than it sounds. Fundamentally, anyone with access to a network segment can saturate it. Like you, I ran an open network for years (this was pre DD/Open-WRT, using pebble linux), and saw some pretty crazy stuff. Eventually I got tired of fighting to maintain a fair and usable network and just went encrypted. However -- this piece and your request for pointers has inspired me to publish my bandwidth sharing and traffic shaping scripts from those days [1], in the hopes that some of the problems can be solved. I really would like to run an open network again, I just need to get things done using my internet connection from time to time. :) [1] https://github.com/acg/wifishape https://github.com/acg/wifishape EDIT: I need to have a fresh look at the high bandwidth encrypted / low bandwidth unencrypted setup you mention, because sharing bandwidth across separate network segments seems like it might work.
