That's interesting, you can see Layer 2 packets but nothing any 
higher?  Weird.

I was almost tempted to get cable anyway and see how easy it 
really is to sniff traffic, but I really don't have the income to 
support two broadband connections (one I trust marginally; one I 
don't trust that is just for 'hacking') right now.
