Marc, I do not argue with 'your half' of the 'answer' you gave to the conference announcement of Jürgen Schm , I just ask for the 'other part': what should we call "a computer"?
'Anything' doing Comp? (meaning: whatever is doing it)? Will the conference be limited to that technically embryonic gadget - maybe even on a binary bases - we use with that limited software-input in 2006? a Turing machine?
