Listen to Gaby. It would be better to do this sensibly. I think Dietmar 
might have written something like this up, but probably for FILEs: you 
might want to email him, or search the web, or his homepage. It might 
also be on boost.

Does sound useful though.

>From man:
       pipe  creates  a  pair  of file descriptors, pointing to a
       pipe inode, and places them in the  array  pointed  to  by
       filedes.   filedes[0]  is  for  reading, filedes[1] is for
       writing.


so filedes[0]  could be linked to istream
   filedes[1] to ostream

...

filebuf(fdopen(filedes[0]..), ios_base::in)

...

etc. 

Could be interesting, I'd be interested in hearing what you come up with.
