Exactly: 2 (or more) squid.conf files, and a shell script somethign like
the following:
(no guarantee that the script is error free, just typing it into
thunderbird now...)

#!/bin/bash

SQUID_BIN=/opt/squid/sbin/squid
SQUID_CONF_DIR=/opt/squid/etc/

if [ ! -x ${SQUID_BIN} ]; then
        echo "Squid-Binary ${SQUID_BIN} is not executable!"
        exit 1
fi

case "$1" in
        work)
                cp ${SQUID_CONF_DIR}/squid.work.conf
${SQUID_CONF_DIR}/squid.conf
                ${SQUID_BIN}-k reconfigure && echo "Squid sucessfully
reconfigured fir ${1}" || echo "Squid could not be reconfigured for ${1}."
                ;;
        home)
                cp ${SQUID_CONF_DIR}/squid.home.conf
${SQUID_CONF_DIR}/squid.conf
                ${SQUID_BIN}-k reconfigure && echo "Squid sucessfully
reconfigured for ${1}" || echo "Squid could not be reconfigured for ${1}."
                ;;
        *)
                echo "Attempting to reconfigure squid for unknown
location called ${1}..."
                if [ -f ${SQUID_CONF_DIR}/squid.${1}.conf ]; then
                   cp ${SQUID_CONF_DIR}/squid.${1}.conf
${SQUID_CONF_DIR}/squid.conf && echo "Wow, location ${1} really seems
to exist."
                else
                    echo "${1} isn't a real place!"
                    echo "Usage: /usr/bin/squidswitch {work|home}"
                exit 1
                ;;
esac

exit 0

Obviously the first two options aren't really needed, but if you have
good bash completion (i think) it might recognize the select case and
complete the options.

Cheers,
