I use it for CVS to connect a file stream (stdout, stdin) to a
socket (via a buffer). So all data send to stdout won't be visible on
the screen, but will be sended trough a given socketed with the right
CVS was build this way and I had to continue it.
But I could imagine that it can be handy when a certain protocol is
used and the protocol part will be done automaticly (in a library) when
data gets written or read. So the user only needs to open the 'device'
and is able to use it by using the default read/write functions.
It won't take much extra space (just 9 words), since it uses already
inplemented functions for the defaults. So that would be a big problem
