Well not to smash any dreams but that is actually FrontlineSMS's github, NOT M-PESA and they are just updating their software to integrate with m-pesa. But it is still interesting that the github hadn't been updated in months and gets an update the exact same time Konen tweets he is hard at work in Kenya, perhaps the deal is with them and not m-pesa? (although m-pesa would still need to bless it)

http://www.frontlinesms.com/2014/03/31/frontlinecredit-project-is-back/In 2014, we will be adding a new module, Payments, to our software suite. Payments will be part of the familiar FrontlineSMS and FrontlineCloud interface, but will allow you to send, track and receive mass mobile payments, vouchers and airtime, wherever you are as well as all the SMS functionality youre used to from us.
The prototype version of Payments, PaymentView, has already been tested by ten organizations in Kenya. It reduced payment processing times for a small savings collective by 85 percent, and increased average client savings by 50 percent.
