One of the signs of a well-thought-out solution is that things that are
impossible to effectively hide are not ineffectively hidden. As you say, in
wireless, everyone can sniff the traffic - radio broadcasts are clearly
publicly receivable. So, if you want any kind of security...

You can increase that cost by improving the quality of the encryption, of
course.

Consider, too, the different kinds of encryption likely to be in place:

Weak access-point-level encryption segregates those who have access to the
network from those who do not have access to the network.

Strong access-point-level encryption segregates each client from each other
client, so that they use different session keys.

That's an awfully progressive admission from an avowed right-winger like
your self, Phillip.

While this scenario started a debate, I have a feeling the most
important point of my original post was lost. So, I'll just reemphasize
it, instead of contributing more to the debate, as I don't have
wireless, and haven't used the access in airports, schools, or even rest
stops along the Interstate.

The important point from my original post is this. If it's not yours,
don't mess with it. Or, as I put it in the original post,
> Don't go playing where you don't belong. In the long run, that's going to keep your job, while someone else loses theirs.


If you don't mess around with other people's accounts, then you don't
have to worry about whether or not someone will 'sniff' your
transmission at a public airport (or anywhere) and use your account to
mess with the accounts that you played with. And, you won't have to
worry about whether or not someone can (or will) detect your activities.
In other words, STAY OUT.
