North Caucasian: One or two families?

Well now that we are sorta on the subject of Caucasianism (and hopefully to steer things back to linguistics)...
 
I'm still learning things here, so pardon my newbie questions. I'm currently investigating whether or not North Caucasian should be classified as a single family (as Sergei Starostin does) or split into two families (Glen's NWC and NEC). I'm leaning toward the latter, and this seems to be the position Encyclopedia Brittanica is taking if you look at their map of languages in the Caucasus: http://www.britannica.com/eb/art?id=10165&type=A. Also, Starostin himself lists a number of roots on his Babel database for that are reconstructed only for West Caucasian (as he calls it).
 
Also, a while ago on the CONLANG list I asked how to properly pronounce the "doubled" consonants of Korean (which I've seen described as "glottalized", "tense", but apparently not ejective). Anybody know?
 
And is this list supposed to be exclusively for IE-related topics, or is this okay?
