It took a few days but I got remote maps working.
So what happens is if you're trying to load a map that you don't already have, it'll query the backend and ask about it. Then it'll download it and load it. No manual downloading, no installing, just playing.
This is actually that fast that you don't even know it's happening most of the time. When you think of map downloads like this you're probably thinking of 10 years ago waiting for 20 minutes while a map downloads from the server at 30kb/s.
This ain't that.
