How to create a virtual device in linux?

Question

My question is pretty much the same as - How to create a virtual file? except I want to do it in Linux instead. I imagine what I need to do is create a virtual device and point the application logging to that device. I'd like to write the device in python or ruby or something else interpreted, if possible.

check out named pipes http://en.wikipedia.org/wiki/Named_pipe

Answer 2

Use mknod. You can create a socket file which your apps can write too. And your logging app would connect to the socket to read from it.
