Could you give some numbers on how many machines and what kind is connected
to how many ethers? "100-800 Kbits", is it per machine or a net-maximum? We
are in the process of building a net of dozen Lispmachines, a couple of
Vaxen, some ten of Sun and a bunch of MacIntosh. Ethernet and some hardwork
will tie them together (I hope). The big question is: Is one Ethernet enough?
