I would agree with everything except that Net.Data is faster to set up than
CGI.  There is extra configuration (mainly the INIT file) that goes along
with Net.Data.  

I may have misunderstood what you meant, but I started out using Net.Data
and one day tried CGI and thought it was much easier and faster, and all the
config stuff is in the HTTP config file, not spread out in the INIT file.
There are also other "tricks" that are hidden in documentation for Net.Data
that are quite obscure.  With CGi, it's pretty straghtforward.

As for the MAP, it doesn't help security.  It may help you "read" the config
a little easier, but once you understand that you can do a map with EXEC or
PASS, it's just the same, assuming you are mapping to a different directory
in the EXEC or PASS.
