How can I set up a new list that sends to multiple existing lists - but only sends one message to each person - even if the person is a member of multiple lists?
a. LSOFT calls this a "superlist"
b. Can "Mailman" do this?
Not directly, no. When all you have is the name of the list, you don't know who any of the subscribers are. Once you've handed the message off to the list (or sublist) itself, it knows who it's own subscribers are, but doesn't know who any of the other subscribers are for any of the other lists.
With some command-line tools to dump the complete set of all subscribers from the selected sublists, then do a "sort -u" on those addresses and then re-import those into another list, you could achieve the same results. But this is not automatic, and would depend on you regularly running some sort of a cron job.
