Joachim - Could Praxislanguage have happened elsewhere?

I do understand that chinesepod.com is about learning Chinese, but could this or a similar venture have happened elsewhere on the planet, say xhosapod.com in South Africa or hindipod.com in Bangalore or friesischpott.de in Germany??

Or is it due to the vibrant economy, enthusiastic people or other more mundane reasons that China HAD to be the place to get things rolling?

Serendipidity, contingency or destiny?
