Some (all?) of the options thrown out require a TCP/IP stack to be added to
the workstations. If they are using NetWare, I believe IntraNetWare has a
built in IPX to IP gateway, hence they wouldn't have to add IP to the
workstations.

However, if they do want use a proxy server arrangement using IP, you have
to add TCP/IP to every workstation and assign every computer an IP address
from the addresses reserved by RFC 1918.

Quoting from Fulton Preston from 6/7/97:
IP numbers for internal use only are:

10.0.0.0 through 10.255.255.255 (Class A Network)
172.16.0.0 through 172.31.255.255 (16 Class B Networks)
192.168.0.0 through 192.168.255.255 (256 Class C Networks)

---These numbers a non-routable, ie they can be assigned by your customer,another one of your customers, customers all over the world. The hitch is,to get out to the rest of the 'net, they'll need the proxy servers aspeople have suggested. 

My favorite proxy/relay server is a collection called Sang's. They're free,use very little overhead, and the HTTP gateway has good loggingcapabilities.
