Unfortunately, one must be root to create a fifo, no?

It should (but is not presently) possible to do this in 4.3BSD
using AF_UNIX sockets.  The socket `file' that is created should
be usable by any ordinary process.  An open() could be translated
into a socket(),connect() pair, and the process would then be
talking to the creator of the socket.

Perhaps in 4.4...
