Wireless Connectivity and bulk resetting of calculators

[mcjtom]

On a calculator, pressing On+Apps+Esc resets most settings to factory default (except for Name and Language, I think), and deletes all the memory. This is especially useful for resetting Home Settings, such as Entry Mode and complex results handling, on the class calculators that students borrow for the class duration.

Is there a way to reset them all at once, e.g. via Wireless Connectivity Kit?

A related question: is there a way of cloning a calculator (or emulator) or some of it's settings or data to many calculators at once?

I presume that updating firmware via wireless settings is not yet an option - is that correct?

Cheers!
