Probably the closest thing to the Unix idea of making everything look like a 
file was the LispM concept of the stream.  Basically, every device you might 
want to write to was implemented as a stream object which supported a known 
set of methods for reading and writing.  If you wanted to send the output of a 
function to the printer instead of the *standard-output*, you'd simply do this:

(let ((*standard-output* *my-printer-object*))
   ...
   )

Simple, no?
