fifo on Windows

Are there any plans to support fifo on Windows?  On my XP
system ("R version 2.1.1, 2005-06-23")

   R> capabilities("fifo")

gives FALSE.

Note that Windows does support named pipes as shown
in the utility:

I think named pipes are only supported on the NT descendants.  We will 
need to drop support for Win9x soon, but I think we still have a number 
of users using Win98 and maybe WinME.

I guess we could add support for features that only work on some Windows 
platforms, but I'd rather not do that until we're not officially saying 
that R runs on Win9x.
