On this topic:
How detached is the underlying processes/functions and GUI from each
How difficult will it be to just pull a different GUI layer on top of
the phone functions?

ie, have commercial Mokos with different frontends - one for my dad who
wants to sync appointments with PC and make calls, thats it - and one
for me with buttons on rotating cubes while watching a movie streamed
via wifi :)

(I havent had time to take a look at die software layers yet, I know GTK
is in there, is X also in? that seems wasteful)
