Just spoke with a friend of mine who's a networking professional. He basically said that CGN is a "fail shortsighted solution", and that it always ends up costing them a lot more than they'd expect, as they need to reinvest in powerful, hideously expensive routers to hold all the NAT tables, or connections start getting dropped when they get old.

I'm not at his level when it comes to things like that, but I trust him, a lot.
