Forget per-interface subnets, that's category 3 material. Category 1 is about connections that should be available from any suitably configured interface. If I want to connect to pool.ntp.org to sync the system clock, or to my company's vpn gateway for telecommuting, or to tor to encrypt my traffic, or to a dynamic dns provider to update my machine's record, I do not care in the least which interface I use. It could be either of my machine's ethernet ports, could be the wireless adaptor, could be the built-in wimax card. Could even be something dynamically configured - a mobile phone tethered over a usb cable, for example. All I care about is that at least one of my interfaces is providing some sort of working network connection. And that's exactly what "provide net" should imply. -Alexandre.
