As one use case, FreeNet Liberec, the co-operative ISP I use, would use the “shared equally” option. The important part for them is that some members access from a single CPE device and others from multiple devices whose IPs are handed out by FreeNet’s routers. There’s a db with mappings from member ID to their MACs, I believe, which is used to generate various config files. So this mapping from member (subscriber) to their MACs or IPs would need to be configurable somewhere, which was already eluded to earlier. Personally, I like the idea of _only_ offering equal sharing, as it’s easiest to implement and serves a social purpose. _______________________________________________ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake
