Heap storage is used only for dynamic memory allocation. All local and global
variables that are statically allocated go to internal ram (stack incase of
local variables)

Same comment as above.

Sounds interesting. But I hope you already thought such a feature cannot extend
to all AVR devices. So maybe XMega A series is what you have in mind?
