This gives me the ability to implement cake. One problem we have is classes that tell everyone 'go download this' that trigger hundreds of people to hammer the network at the same time (this is both a wifi and a network bandwidth issue, wifi is being worked on) The network is pretty flat, a couple of subnets each on ipv4 and ipv6. Any suggestions on how to configure cake for this sort of environment where there are so many devices? David Lang
