Both EtherPeek and NetMinder Ethernet will grab packets from all nodes off an
ethernet.  Etherpeek is by the AG Group, I believe their address is
ag.group@applelink.apple.com, NetMinder is by Neon Software, their address is 
d5969@applelink.apple.com.  

Both are commercial products and have served me well as a "poor man's sniffer".
