I was refering to the network as say your home computer. I was trying to make the point that you should be alot more concerned with someone sniffing passwords other than just your perlmonks password, or with something potentially worse, say using your netbios shares (or any other vulnerability for that matter) to "hijack" your computer.

The point is, that I often use my notebook from other networks(with wireless lan, so no switching) where I don't know everyone. I do know that most of these people there are able to use techniques to get any information that may give some fun, such as account information. I already use other means such as pop3s (and I don't have open netbios shares...) to minimize open vulnerabilities, and I wondered if it was possible to do so with perlmonks.
