Thanks cfajohnson, but that back slash prevents LINENO from ever being expanded:
joe@rose:~$ MYNAME=joe
joe@rose:~$ MYPID=$$
joe@rose:~$ LOGGER="/usr/bin/logger -t $MYNAME[$MYPID](\$LINENO) -p daemon.error"
joe@rose:~$ echo 'test' | $LOGGER
joe@rose:~$ tail -1 /var/log/daemon.log
Feb 18 01:40:27 rose joe[26479]($LINENO): test
Am I missing something?

NAME
logger -- make entries in the system log
SYNOPSIS
logger [-is] [-f file] [-p pri] [-t tag] [message ...]
DESCRIPTION
Logger provides a shell command interface to the syslog(3) system log module.
Options:
-i Log the process id of the logger process with each line.
-s Log the message to standard error, as well as the system log.
-f file Log the specified file.
-p pri Enter the message with the specified priority. The priority may be specified numerically or as a ``facility.level'' pair. For
example, ``-p local3.info'' logs the message(s) as informational level in the local3 facility. The default is ``user.notice.''
-t tag Mark every line in the log with the specified tag.
message Write the message to log; if not specified, and the -f flag is not provided, standard input is logged.
The logger utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
logger System rebooted
logger -p local0.notice -t HOSTIDM -f /dev/idmc
SEE ALSO
syslog(3), syslogd(8)
STANDARDS
The logger utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
