Initially, yes. Notice that even biologically realistic simulations can run
at significant superrealtime, if dedicated hardware is used. To make it extra
clear: the speedups I mention are advanced state. They don't have to take a
lot of wall clock time, though, because it's a positive-feedback process.

The constraints of computational physics dictate an optimal hardware shape, which goes
along with encoding (there's some leeway, but not much). If speed is a
fitness component, mature state describes a very similiar hardware and very
similiar encoding for all infoprocessing systems due to convergent evolution.

Yes. Assuming communication is considered worthwhile, there will be
communication. However, there will be a tendency for uploads evolving and
radiating into incomprehensibility, possibly very rapidly so (again, in wall
clock time), given the projected speedup factors.
