Thanks for the insights. The size of the team (whether in-house, in-country, or across the globe) has also been weighing on my mind lately. I've read that book, and I am convinced that we'll get diminishing overall productivity from each new developer we add. But we're stuck in a place where we need to try something: the business is demanding more productivity, and of course wants it at minimal cost. I think my new boss gets that, and that's why he extended the offer for this "extra" help. I will definitely go back and check out the pages you pointed out. Outsourcing or multi-site development wasn't even on my mind back when I read the book, so I had forgotten that there was specific data about it in that model.
