NTSYNC seems quite cumbersome to use for your own linux software though

> The ntsync driver creates a single char device /dev/ntsync. Each file description opened on the device represents a unique instance intended to back an individual NT virtual machine. Objects created by one ntsync instance may only be used with other objects created by the same instance.

So you need a server process that can open the char device and hold onto the fd that you can then request through a Unix domain socket.
