Custom filesystem implementation

Hi to all,
we have to implement a custom filesystem for a new customer.
A couple of years ago we implemented something similar through the Dokan framework.
Now, because Dokan is in end-of-life till 2011, we want find the right technology to do the same for Windows 7/8.

Anybody tell us what kind of technology we have to use (File System Filter Driver, File System Driver, Network Redirector Drivers, etc) to implement something like Dokan.

Thanks,
Marco
