I've been looking for something like this for our product (SaaS database client, shameless plug: http://www.jackdb.com/) as security during network transit is obviously a big deal. At the moment there's is no explicit SSL/SSH tunnel so it relies on the underlying driver to handle.

Being able to plug into something like this would be useful if it can automate/offload the client side VPN setup and simplify things for a client adding a new connection.
