It makes managing networks a lot easier, since the authentication done by PPP is able to look up any end user specific information required (ie static ips and routes), while the access part of the network is a fairly generic config that uses switchs and things like the GVRP. Without that, the configuration of any aggregation switch becomes a huge management nightmare. If you don't want the overhead from this kind of scaling, stick it under a config option, but please don't stop other people from pushing Linux into new uses which have these scaling requirements. -ben
