** I assume it is myth, but I've never heard anyone from Google make
any statements that definitively debunks it. Debunking this pervasive
among webmasters and "SEO Experts" myth sure would be a very UN-evil
thing to do if true (Hint hint you Google-folk!)
Actually they did, once, in an obscure place:
Whenever I refer customers to that, they just tell me oh,
that's from 2002, my SEO person knows that Google penalizes
for sharing IP's now.
I guess Google needs a time stamped banner on their site
that says "As of <time>, we do not penalize for sharing IP's."
so SEO 'experts' can't argue it.
