openvpn tap driver in close-source project

[Ronex]

Hello,

I didn't have much understanding over licensing, So I find it better to ask it over here.

I need to use OpenVPN tap driver for tap interface based project. But as far as I know it is licensed under GPL, that might needs my project to go for free and I can't use it commercially, So there is any LGPL kind of license for OpenVPN tap driver. Or I need to develop my own driver ?

Although its a kernel driver and my project don't have to link it with program; my code uses just the usual Windows API calls to talk to it. But still it need to be distributed with it.

This is a last option (i am not expecting for this) but still is there any documentation which could help me in developing my own tap-driver.

Any Help or Pointers will be appreciated.
