Well, I realize it's bad form to reply to one's own message, but I  
came up with the following for tcsh users:

==================================================
if [[ -d $TM_SELECTED_FILE ]]; then
    TM_PATH="$TM_SELECTED_FILE"
elif [[ -f $TM_SELECTED_FILE ]]; then
    TM_PATH="`dirname "$TM_SELECTED_FILE"`"
else
    TM_PATH="`dirname "$TM_FILEPATH"`"
fi

tmpfile=`mktemp -t tmvars`
env | grep -v '^TM_' | sed 's/=\(.*\)/ "\1"/;s/^/setenv /' > $tmpfile

osascript <<EOF
    tell application "Terminal"
       activate
       do script "cd '$TM_PATH'; source $tmpfile; rm -f $tmpfile;  
clear; pwd"
    end tell
EOF
==================================================

Not perfect as it slams everything into the environment, not just the  
project variables; As well, its escaping of the environment variable  
values is naive. And it assumes tcsh. But it's a start.

If this seems generally useful, I'll fix it up to determine tcsh vs  
bash and handle proper escaping. Dunno about how to determine project  
environment variables though. Maybe something like:

VAR="${VAR:-$VAR}"

which will only set the environment variable to the new value if it's  
not already set, as least for bash. I don't think lame tcsh has such  
a convenient construct (yes, I really need to switch shells, been  
meaning to for years now).
