I immediately thought of this when I saw this tribe. The gomchen tradition in bhutan (also known as ngagpa in other parts of the himalayas), they are trained in the dharma and also live in the community with families and everything, so they cross over into both monasticism and lay lives. There's a good article on this, but its in pdf so here's the link:

The article talks about the gomchen tradition in relationship to the concept of Gross National Happiness that Bhutan is using as an alternative to western conceptions of development, but also gives a good overview of the gomchen tradition.
