For how amazingly useful it is... networking is kind of hacktastic at the protocol level. It's a bunch of layers that don't know anything about each other, and any even slightly unusual setup is a nightmare of manual configuration. It happens to do exactly what people do with it very well, central web services and some limited LAN stuff on the same subnet. I almost think things would be better off without the OSI model, if we were to start over. Just one CJDNS-like mesh, with native support for encryption, firewalling, pairing and discovery, all in one place, under one version number. Everyone talks about the flexibility but I'm super not convinced things like 6LowPan are a good idea. Just being able to say "This isn't IP and has no way to get on your network" is a big advantage of things like ZigBee, in a world where nobody really trusts this stuff.
