I've spent a while working with the faces & clip plugins and am glad to announce that I've actually got it working well (and in a repeatable manner). It looks like there's a slight glitch with the tagging part out of the box. I think the "field to store tags in" doesn't get updated in the back end even when you change it in the front end. Or else I did it wrong.
Anyway, I'm just so happy that I got it working that I wanted to share. The attached image shows that (fed with a video) the clip service decided that "powder", "mountain", etc . . . were good tags and "Snowboarder on slope" was a good title.
I think that's mighty impressive.
I'm planning on posting up some notes which consolidate the whole clip & faces thing in the near future The steps I have will take someone from no RS at all, to an RS install with face & clip installed, running automatically as services and logging their transactions.
