With Google ending support for XMPP in less than two months, why doesn't Obihai make a new Obitalk that's a combination of Raspberry Pi and GVmate?
GVmate is a USB device that connects to a computer then it connects to a phone; and best of all it doesn't use XMPP. So it will work after May 15, 2014. The only downside to GVmate is that it must be connected to a Windows computer and the computer must be on in order to make and receive calls. Now this is where Raspberry Pi comes in.
Since Raspberry Pi is a computer, all Obihai would have to do is integrated GVmate into Raspberry Pi and voila. Now you've got a standalone device that doesn't need to be connected to a desktop or laptop, and that will work once Google ends support for XMPP.
If Obihai plays their cards right, Google ending support for XMPP could be the best thing that ever happened to them. All Obihai would have to do is make an Obitalk 2.0 that's Raspberry Pi + GVmate. Then bang, you've now gotten all of your customers to buy your product again.
I would pay for a new Obitalk that doesn't need to be connected to a desktop or laptop, and that will work after May 15, 2014
