Actually, he can.  If you're talking about using WEP, he just needs the
key.  If you're talking about IPSEC, it doesn't stop Barney participating
in the link anyway - it only stops him sniffing traffic not destined for
him.

Not that I especially think we need to encrypt traffic on transit links at
the link-layer, but it would make life difficult for the bad guy that
wants to spoof traffic.  This may or may not be a problem...

What WEP would do is make it a lot harder for Barney to work out that
there _was_ a link in the first place.  Of course, he could always use the
other resources (i.e. web pages) to find Joe and Fred.
