Depends on your VPN client.

You can open a Windows PPTP VPN by executing a command..
Something like: rasdial "vpn name" username password

The other option is a SSH tunnel.  Probably requires a Linux server at

We used to do this in one of our products but last week switched to https.
(or some other IPsec, haven't had a chance to look at it yet).
