Well, there is the obvious "be part of the solution" and educate them.
Seriously, while we tend to avoid the MUP's on the weekends, there is one section of our long ride where the traffic on the MUP on a Sunday afternoon is not as bad as the traffic on the roads. So we ride the MUP. On that section there are alot of families with small kids. Most of the parents are pretty good, but occasionally there is the squirrelly kid too far ahead of the parent. My job at that point is to slow down and educate if I expect the kid to grow up and be a responsible MUP-per.
A moderate volume (too loud and you scare 'em) "on your left" works if they're trained; if they start to weave, then you do the "steady, stay on the right side, ride straight, keep it steady" blah, blah chatter as you pass them followed by a "good job"/"keep it up" kudos when you're past. On a weekend, the MUP isn't yours, it is theirs. Expect to drop your speed and take the time to teach.
