Borrowing from one of the latest of Jacques' posts, I just want to add that,
the nature of the logical connections between the observer-states can simply
be considered to be computational steps as performed by a Turing Machine. The
validity of a computational step, however, is not absolute and independent of
the observer. What is and what is not an allowed computational step is
definitely in the eyes of the beholder, and depends on his state of mind (set
of axioms and rules), and even on his space/time/cyberspace/timeshare
occupancy. For example, the clock of the Turing Machine could tick along
space intervals rather than time intervals. Or the operation of the TM could
be listed as hardcopy in a book rather than being executed in time.
Correspondingly, for the observer to perceive such a strange TM mediated
consciousness, he would have to have his own clock also beat along space
intervals or his own operation also listed as hardcopy, with the
interactions between himself and the TM taking place in the appropriate
space/time/cyberspace/timeshare medium.

Computationalism can be recast in a relativistic framework to take all this
into account.
