I've got a machine that seems to be running perfectly, except that I'm unable 
to get any bits in or out across the NIC.  (The NIC thinks it's sending bits 
to the router; the router thinks it's sending bits to the NIC.  Nothing's 
travelling back on the wire, and yes, I've tried all the obvious things.)

Is this the sort of problem/machine it would be reasonable to bring to an 
Installfest?
