:zz: New cell IDs-- a key question

Hi Edward--

You strike at the heart of matters when you ask--
>Is it easy for external programs to generate new ZZ cell ids?

The answer: we want every unit to be able to generate unique IDs,
 so that cells can be transported with full identity maintained.
 That will be either a prefix or suffix with the machine ID.
 (Undecided which-- suggestions?)

Note that that makes the cell unchangeable (unless the ID changes,
 in which case it's a new cell, of course).

Best, T
