 2.  We see it as a DATA LAYER for a new rational system of computing.  The 
grotesque inconsistencies and complications of files in their present form-- 
consider, for example, the issues of readdressing among downloaded HTML files-- 
may be replaced by a clean, table-like arrangement which keeps track of things 
more easily-- and which bright non-tekkies can deal with.
 Tomorrow's computer environment will involve vast, constant media downloads.  
ZigZag structure offers a scalable, rational system of registration and storage 
which can handle this very cleanly.
 3.  A new form of SPATIAL PROGRAMMING, table-driven in zzspace, may simplify 
programming and computer environments in general.
