I don't have to do this much from Windows, but the last time I tried, the restart options on openvpn made it much more reliable than trying to keep PPTP or a ssh tunnel up. It can be installed as a service or it can be started from a system tray icon. It ran for years and rarely needed any admin intervention, which was just as well as it was a 2 day trip for its admin to reach it!
Distributing openvpn.exe and the necessary configuration, keys and certificates isn't that hard if you have some distribution channel already set up. It also means you avoid the reported PPTP security horror stories.
Hope that helps,
