You can HP to the list of hub vendors which have a secure model. Does
the NCR hub allow more than one ethernet address per port, the HP does
not. How do you deal with the case of more than one machine per room?
Do you have multiple jacks? One jack per bed? How about the student
with 2 pc's?
Also 10,000 nodes divided into a half-dozen ethernets gives greater
than 1000 nodes per ethernet, is that right? How well does that work?
thanks,
mark
