In a nutshell - no, you can't. HOWEVER, pipes are now Streams based and
you CAN push streams modules on them.

There was (is) some group/person/university/company that produced a 
file system model that was stream-liked base. I think this was the interface
between the FS and the device drivers. I don't think the model included
the interface between the FS and user programs.
