We've seen people on the list mention that 100M interfaces are barely
enough to drive 30 client machines from one server and that they see
a big improvement from changing to a gig uplink between server and
switch.  Your WAN link is going to be an equivalent bottleneck but
for all clients, not just those connected to a single server.  I'd
take the 100M per 30 clients as a minimum.  Wouldn't it have been
a good idea for the people making the decision to ask about the
requirements first?
