Interesting. Certainly merits a shot In old days Nyt and post was free for over seas markets. Economist and FT do have country/ city (?) specific pricing to sweeten the hit. This makes it affordable in terms of PPP. Or they bundle their offerings with local partner in local currencies.

This leverages the zero marginal cost of the nth customer principle. But dynamic pricing, not necessarily, real time but based on some basic segmentation viz. Pin code, IP address, duration, landing page, cookies, clickstream, etc could be a starting point to start semblance of charging for content, after the first 7/10 free articles.
