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

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).

AUTHORS

     OpenSSH is a derivative of the original and free ssh 1.2.12 release by Tatu Ylonen.  Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos,
     Theo de Raadt and Dug Song removed many bugs, re-added newer features and created OpenSSH.  Markus Friedl contributed the support for SSH
     protocol versions 1.5 and 2.0.  Jonathan Amery wrote this ssh-argv0 script and the associated documentation.
