Thank you all for your input...
Here's my thinking: I'm waaaaaay too busy to start a troop, and don't really want to join another troop as co-leader, just for the purpose of changing the way the leader does things (that seems to be a great path toward conflict, NOT something the girls need to see!). So, we go Juliette and work with the troops to help make area GS more cohesive and more energized. For example, I plan to organize and conduct the Bureau of Land Management's "Girls Get with the Land" patch next year, and possibly do the EPA Waterdrop patch for other area troops as well, work on some other outdoor, "more robust" patches and badges with my daughter and invite and involve the other troops ~ hence strengthening the girl-group bonds as well as encouraging my daughter to explore all her interests. Nobody gets jealous or feels like they are in a competition, nobody feels I'm pushing them to change their troop, everybody's happy.
Juliettes will also give our family the freedom and flexibility to do all things Girl Scout (GS camp, major outings, patches & badges) while not being bogged down with permission slips, money issues, dues, registration forms, etc. so on.
I've found a few resources online, and was hoping to hear from others about their experiences with Juliettes, whether at a council level, a troop level, or as the parent of a Juliette. :-)
