As long as you're using PSExec, I would just stick with it. You can get the ID field pretty easily given a username e.g.:

$username = 'joe'
$results = psexec \\remoteMachine -u adminuser -p password query session
$id = $results | Select-String "$username\s+(\w+)" |
                 Foreach {$_.Matches[0].Groups[1].Value}

psexec \\remoteMachine -u $username -i $id -d notepad.exe

Note that you want to use -d with PSExec otherwise it will wait until the launched program exits.
