Hi Palm Piloters--
I think now is not the time for a port, because both
the Palm Pilot and ZZ are going to be evolving significantly.
The Official Sync Method for ZZ cells is going to be the
Slice. A slice is a set of cells (not nec connected amongst
themselves, but expected oft to be) which can be brought in
connected to your other stuff. Or, more precisely, an
Outer Slice lives on disk and may be brought in to connect
to your main stuff (the Home Slice).
There is an expected implementation hierarchy for slices, not yet
written up here. (The usual time problem.) The design for
fulll-capability interpenetrating slices is in the infamous memo
of July 98.
