BTW, please consider contributing to WinFsp :) You do not have to contribute to the core project if you find the license unpalatable or any other reason. But there are other ways that one could help. Creating a C# or Java wrapper would be very useful, for example.
The cygfuse project also needs help and this one intends to work with both WinFsp and Dokany:

> Many of your potential contributors may also lack the required operating system to do the work...
That is an interesting thought. I wonder if I could spend some time to try making this compile on Win7.
I'm wondering how tricky it'd be to create a C# FS implementation that supported both Dokany and WinFsp from the same codebase.
That's actually a cool idea.
The API's are not dissimilar as both API's were designed for Windows. If you decide to look into this you can count on my help and support.
