tcp ports are much more versatile, you can expose it to the outside world as opposed to unix sockets. Now exposing an nfs server to the outside can lead to interesting possibilities: for example you can implement a local fuse file system which can be mounted remotely through the NFS. It's highly not recommended at this moment because there's no authentication implemented

Is there any fundamental reason you couldn't do both? Presumably local sockets have less overhead (and I do prefer not to open ports unless needed).
