[Discuss] Looking for a user space NFS implementation

[markw at mohawksoft.com]

For reasons beyond the scope of this message I am looking for a well
supported user-space NFS implementation. The only somewhat viable one I
have seen is unfs3, and it appears it hasn't been modified since 2009.

Does anyone know of anything being actively developed?

Additionally, does anyone know of a user space NFS server that will follow
symlinks instead of presenting as symlinks?
