Re: Wireless ISPs

[D B <geggam692000 () yahoo com>]

Everyone is so busy trying to outgeek the other they
are missing the issue.

An 8 year old with a laptop who downloads netstumbler
could read peoples emails with no difficulty from an
ISP who offers no encryption ( god knows that 8 yr old
can kick my ass on a video game )

My main issue is preventing the casual observer from
stumbling in, similar to locks on a screen door.

Not really a security issue to be relied on but does
prevent casual entries.

Always hate debates with geeks unless they are close
enough to break their nose when they start trying to
outgeek the next.
