And how is that any different than an user just using an exchange from their portable device?

The only difference I see is just us paying for something , we are already getting for free.  

@ZEIT, Our goal here is to make sure the coin network works and is secure, that's it.
(The Same Way Linus Torvalds only focus is the Linux Kernel.)

Everything else we are leaving up to 3rd party providers,
ie: Offchain transactions, Anon transactions, Mobile device support
None of these need direct support built into the code, all can be handled by 3rd parties.

Here we focus on the main goal:
a fast working coin network with ample transaction capacity that is efficient and affordable for the entire world not just the rich elite.
Anyone want more, feel free to build a 3rd party service and we will update the OP.
