psion like keyboard discussion

I dream about good keyboard for non only latin languages

What exactly is needed for that? Please give some details as it's an area many of us are more or less clueless about. Is it a matter of having the right key map and input method or are there other considerations like needing specific modifier keys present for the input method to work? I've already suggested a blank keycap option and programmable key mapping which might help of there isn't a fundamental issue with layout or number of keys.
