They used to send a `technician' out to install a free cable
outlet and the software for you.  At the time, I was able to get
them to give me an IP address and other relevant numbers (along
with a crappy NIC) and go away.  These days, the technician shows
up, tweaks a few wires to activate your cable outlet, and hands
you a Windows/Mac CD that you have to use to register your
account.  So effectively you do need a Windows box, but I have had
no trouble swapping NICs.  I have also used the same NIC (and
cable modem) from two separate accounts on different subnets.
Their DHCP servers used to be picky about the hostname you sent
them; perhaps that has something to do with it.
