We've stripped zips in the past temporarily as circumstances
dicated but after Monday we're looking strongly at making
it permanent.

It would be nice if we could just strip zips containing
executables but our mail server, Mirapoint, does not support
this. We've requested an enhancement to support this. Sadly,
we'd also have a need to handle password protected zips in
some way.
