	i'm surprised that you concede even this point, Henry!

	media considerations can make 802.4 more attractive in some cases.
	i think some factories run video information across the same
	cables which carry the token bus traffic -- to keep an eye out
	for errant robots & parts.  of course, ethernet can run over
	broadband cable as well -- but the distance limitations persist.

	any comments about broadband cable plants and standards ?

	this brings up another big difference between 802.4 and 802.5 -- 
	.5 is baseband, while .4 is broadband...
