You can bind two 100 MB NIC with the same MAC address/IP address and in
essence have a 200 MB NIC to the network. Cisco does this with
'EtherChannel' and their 3500 series switchs support it. I'm not sure if
the linux 2.4 version is compatible though. You can also load balance the
IP's with a LVS type layer load balancer but you can't get one session 200
MB unless they open up two different sockets. IMHO it is better to have
the binding at layer 2 instead of layer 3 or 4
