It's the best that's available for it right now; if that's not helpful, I'm not really sure what is. That is, unless you were expecting me to write a Windows ZFS driver with read/write capabilities myself and provide a link to that ;)
I run a virtual machine exported over samba for ZFS, I think that's much better than a read-only version.
But if you're going to give a link to something that doesn't meet basic requirements, say so. Otherwise it looks like you're disagreeing with the claimed lack of windows support.
