Elegant. And nothing new required.

Perhaps far more than 50%.
Nothing would surprise me w/r zombots, BUT .. I suspect that most run as fast as
they can, ergo what Marc *might* be seeing as an apparent 'tactic' of slowing
down a session could just be that some of the WinBoxen victimized might have
seriously dodgy resources - eg: links with high packet loss rates and/or dial-up
lines.... even a box so overloaded with other infections and 'applications' that
it is hard-pressed to keep up appearances smtp-wise.
