While WebNFS itself did not gain much traction, several important WebNFS features later became part of NFSv4, including use of port 2049, and the concept of a fixed "root filehandle" (which evolved from WebNFS public filehandles and allows exported filesystems to be accessed without needing the MOUNT protocol to learn their individual root handles first); both together allow NFSv4 to function without the Portmap service.
