I would like to see the mixin as well.
Also, just to clarify something: this is a complete rewrite of simplewallet and not a wrapper, correct? Is so, then it must be able to connect to a daemon on another device, correct? If so, then there is no reason the wallet will not be compilable for ARM, correct? If so, then it will be truly cross platform (Windows, Linux, OSX, Windows Phone, Android, iOS), correct?
If not, please let me know where my enthisiasm gets derailed.
One of the things we've spent an inordinate amount of time is abstracting stuff away from simplewallet. This has resulted in us being able to build rpcwallet, which takes the rpc guts out of simplewallet and gives it a much more robust frame for automated environments.
The GUI will use the same libraries the daemon does, so it will provide the same underlying functionality without the need for a second instance of the daemon to run. This is NOT the right solution for mobile devices or even very low power devices. That said, the fundamentals that we're abstracting and working on now will allow a rich variety of interfaces to exist, all inheriting and using the same functionality without worrying about underlying application logic changes.
