It might be interesting to look at --

http://www.xanadu.com.au/mail/zigzag/msg00253.html

a mail from Brent Turcotte dating from last October which dealt with
similar thoughts. We might add that the cells should be transient. And,
there might be some nasty interactions with versioning and the global ZZ
space (ZigZag's docuverse, should such a beast ever be specced). Other
than that, just keep in mind that the cells should be transient UP TO
THE MOMENT WHERE THEY'RE LINKED TO A NON-GENERATED CELL, in which they
should become ordinary cells, BUT STILL CONNECTED TO THEIR GENERATED
NEIGHBOURS.

Probably useful for many things, if it's done in a clean and sufficient
way..
