Lest anyone misunderstand me, I like the EtherPort II.  I have one in
my Mac II, and so far the FTP performance that I've measured has been
limited by the other end (at the moment, a 3B2/300... Ick :-().
Anything that doesn't overload the 82586 isn't a problem.  However,
very fast hosts can make it an unhappy camper.  Ephraim Vishniac, for
example, noticed that he can talk to a Sun just fine, but gets
miserably slow performance when talking to a VAX 8800 (Ephraim: please
correct me if I'm wrong).  Somehow I doubt it's the VAX that is the
bottelneck... :-).  If the hosts you're talking to are not fast enough
to send more than two back-to-back Ethernet packets, you should be
fine.  If they are though, you might want to try various boards in
your machine to see how they work *on your network* before you buy a
lot of them.

Disclaimers:  We sell TCP/IP software for the Mac.  So does Kinetics.
We don't sell hardware.  We like and use Kinetics hardware, in fact.
