I get the same error dialog with -r.  Also the manpage does seem to
indicate that I can specify a named pipe with -i:
-i  Set the name of the network interface or pipe to use for live
    packet capture.  Network interface names should match one of the
    names listed in "netstat -i" or "ifconfig -a".  Pipe names should
    be either the name of a FIFO (named pipe) or ``-'' to read data
    from the standard input. Data read from pipes must be in libpcap
    format.
Any other ideas?
- Mike
