What is behind the preference to roll your own rather than call existing 
purpose-built command-line tools from LC with shell()?

Your chunking described in your latest post seems the way to go, AFAIK 
pretty much how other tools would handle it.

Another option:  if you're in an environment where even log files 
require strong encryption, could you pipe log data to a separate secured 
log server instead?
