Being morris offspring (no capitalizations here) myself, I think the idea's pretty cool, actually. I hope someday they make it across the water. There are morrisers and morris watchers here, too. I think it's equally important to have "traditional" stuff keep going, whether the people involved are the genetic relations of former morris dancers or not, as well as having people who try to make it slightly more accessible to the general public, especially if they're having a good time in doing so.
Of course, I'm probably less attached to traditional morris anyway, being an Amer-kin myself, because over here instead of doing the traditional dances of our hometown (being that our hometown doesn't have any), we import other people's and futz with it. On the other hand, one could argue that's folk tradition...
