Answering my own post subsequent to finding an answer - this is not actually possible. A FIFO is s kernel inter-process communication mechanism and as such it apparently alters the device map in the kernel on the local system. Because of this, writing to a FIFO across a NFS mount to a remote machine will not work because the local kernel is not aware of the FIFO in its device map.

FAXLOCK(8C) FAXLOCK(8C)
NAME
faxlock - tell a HylaFAX server to switch to LOCKWAIT state
SYNOPSIS
/usr/sbin/faxlock [ -q dir ] modem
DESCRIPTION
faxlock sends a message to a HylaFAX faxgetty(8C) process servicing modem telling it to change its state to LOCKWAIT
The specified modem can either be the name (typically the last component of the terminal port the modem is attached to), or the full name
of the associated FIFO named pipe file, e.g. ``FIFO.ttym2''.
OPTIONS
-q dir Use a spooling area other than /var/spool/fax.
NOTES
When faxgetty changes it's state to LOCKWAIT, it will start looking for the UUCP lockfile for the device, and when the device is no longer
locked, proceed to re-initialize the modem.
FILES
/var/spool/fax default spooling area
/var/spool/fax/FIFO fifo for contacting faxq
Consult hylafax-server(5F) for a complete discussion of the structure and content of the spooling area.
