Summary: Ameristar has IP/TCP for Amiga, they have several flavours of Ethernet/ARCNET hardware, etc.

	Yes, Ameristar does this.  Only item not handled NOW is dir.  We
	call it inet:, and you get to IP, TCP, UDP, etc by incanting
	inet:tcp/addr/port, inet:udp/addr/port, etc.

	The problem with device driver/library implementations of Phils
	code is that the code was designed to be single threaded commutating
	loop.  To play as a device library requires either toggling a
	semaphore on entry to any network routine (minimal changes to
	code), or identifying and then placing monitors around critical
	sections in the code (mucho changes to code).

Gheesh, I'm beginning to think there is a 60 dB Ameristar notch filter
at UDel :-).  Yes, there is a SCSI <-> Ethernet box - made by Kinetics.  The
cost to Universities is $1125 ($1250 for commercial folks) for the 
thin Ethernet version (thick Ethernet costs ~$125 less).  As I've said 
before, though, the cheapest way onto Ethernet copper for the Amiga is 
the Ameristar A2000 board: $699. It plays on thin Ethernet without 
setting you back extra bucks, and as always, I have a driver (that I wrote 
for a port of KA9Q's code to the Amiga done before Lou's time) that 
you can have for free..

PS.  I do development for Ameristar, so consider this posting biased..
