Currently (as of February 2013) this is not possible: your application will have to connect to TWS via the API, you will have to manually launch TWS using client credentials (user ID, password, second token authentication, if applicable).
We considered providing a programming interface where third parties can offer our customers additional services similar to what you described, but at the time this did not justify our investment.
The best way forward is to send a feature request through our feature poll ( http://www.interactivebrokers.com/en/?f=%2Fen%2Fgeneral%2Fpoll%2Findex.php ), describe your setup / objective and who you represent, and appreciate it well.
