My retrieval script uses a timeout similar to yours. The process id is stored in $! though:

Code:
    if [ $SERVER = $JUMP ]
    then
      scp -q $SERVER:$SERVER/$CONTENT $SVRPATH & > /dev/null 2>&1
      PID=$!
    else
      scp -q $JUMP:$SERVER/$CONTENT $SVRPATH & > /dev/null 2>&1
      PID=$!
    fi

# wait for the specified number of seconds for scp to complete
# if the timeout is exceeded, kill the process and move on to the next box

    while [[ $TIMEOUT -gt 0 ]]
    do
      /usr/bin/ps -p $PID > /dev/null 2>&1
      if [[ $? -ne 0 ]]
      then
        break
      fi
      TIMEOUT=$(($TIMEOUT - 1))
      sleep 1
    done

# if the timeout reaches 0, then the process was killed. Report something.

    if [[ $TIMEOUT -le 0 ]]
    then
      echo "ERROR: Unable to connect to server ($PROGNAME)" >> $SVRPATH/config.status
      chmod 664 $SVRPATH/config.status
      kill -KILL $PID
    fi

timeout

TIMEOUT(1)							   User Commands							TIMEOUT(1)

NAME

       timeout - run a command with a time limit

SYNOPSIS

       timeout [OPTION] DURATION COMMAND [ARG]...
       timeout [OPTION]

DESCRIPTION

       Start COMMAND, and kill it if still running after DURATION.

       Mandatory arguments to long options are mandatory for short options too.

       --preserve-status

	      exit with the same status as COMMAND, even when the

	      command times out

       --foreground

	      when not running timeout directly from a shell prompt,

	      allow COMMAND to read from the TTY and get TTY signals; in this mode, children of COMMAND will not be timed out

       -k, --kill-after=DURATION

	      also send a KILL signal if COMMAND is still running

	      this long after the initial signal was sent

       -s, --signal=SIGNAL

	      specify the signal to be sent on timeout;

	      SIGNAL may be a name like 'HUP' or a number; see 'kill -l' for a list of signals

       --help
	      display this help and exit

       --version
	      output version information and exit

       DURATION is a floating point number with an optional suffix: 's' for seconds (the default), 'm' for minutes, 'h' for hours or 'd' for days.

       If  the command times out, and --preserve-status is not set, then exit with status 124.	Otherwise, exit with the status of COMMAND.  If no
       signal is specified, send the TERM signal upon timeout.	The TERM signal kills any process that does not block or catch	that  signal.	It
       may be necessary to use the KILL (9) signal, since this signal cannot be caught, in which case the exit status is 128+9 rather than 124.

BUGS

       Some platforms don't currently support timeouts beyond the year 2038.
