This is assumes that the number of hosts attached are constant. If the number of hosts grow exponentially, then the bandwidth required of the network will grow faster than exponentially.

I didn't notice any exponential growth of hosts in my home (although my bandwidth grew from 14.4 to a T-1 meanwhile). The exponential growth of _connected_ hosts was mostly fueled by connecting existing machines and by new computer users. Unless you have a recipe for getting people to breed much faster the end of that trend is pretty much in sight (witness PC makers killing themselves in scramble to the way-less-than-affluent market). --vadim PS. If you do know that secret recipe please keep it secret :)
