The standard says you are almost 40 foots away (If I remember well, they were 110 meters maximum from jack to jack)

IIRC the mathematics involved give a maximum cable length of ~136 meters (~445ft) based on ethernet timeouts vs propagation time.
Should be interesting to see if it works in practice...

Owen, perhaps I'll get lucky then, I'm under 445 feet. I figured there was some give in the 100 meter limit that's quoted everwhere. Was thinking about signal attenuation, but propigation time is a harder limit. --Joey
