Just read this article talking about Facebook's push into getting a piece of the action in mobile payments. Which got me thinking, why don't they just buy Mpesa from Vodacom and Safaricom? and if they do, what would happen?

I'm curious on what the effect would be on Mpesa if they did buy it out, or if they couldn't, the obstacles that would prevent them from acquiring it, legal or ortherwise. They did just spend a ton on whatsapp, money really isn't a problem for them!

Thoughts?
