Wel in fairness if we're talking about an SSL server that's taking credit
card orders, I'd assume it'd be switched as much for bandwidth to it's
database server as anything else.

If you're talking about someone who can get onto the subnet of the web
server and have permissions to go into promiscous mode then I'd say he's
either:

* A dodgy dishonest sysadmin or
* they have a net/sysadmin who is crap and hasn't stopped anyone else from
doing this

In either case, I wouldn't be happy sending my credit card info to be
stored on their machines by ssl or otherwise.  Chances are the guy has
acces to the db too.
