A file is an object that supports the methods open(), read(), write(), and a few others. That's about a generic as you can get.

If I write <data> /dev/net/tcp can I read and get <data> back ?

Can I append <data> /dev/mouse ?

Sharing {open,read,write,close} interface, but with exception and different semantics leads to a weird flavour of genericity.
