I'm currently working on adding dynamic sublists (dlists) to mailman 3. It's a feature that Systers wrote for Mailman 2.1 that allows dynamic creation of "sublists" that people can subscribe or unsubscribe from within a list. Currently it uses the email address to do the filtering much like you described, but doesn't do the prefixes. Robin and I hoping to have the port of the dlist code done soon, probably in January, with the goal to have the code be part of the Mailman 3.1 release. Once it's in I think it wouldn't be too much more work to add the bracketed prefixes, perhaps as a configurable option for dlist enabled lists. It might even be a feasible project for a Google Summer of Code student at that point. So, in short, some of the necessary code already exists for Mailman 2.1, it's actively being ported (as in, Robin and I are trying to get together biweekly and hack on it), and it's probably not as huge an undertaking as you imagined as a result.
