In my experience, OSX's implementation of NFS is buggy as well. It's not uncommon for my NFS server to simply give up and stop responding to requests from the vm. Trying out Fusion's share has been on my todo list for a while. I'm a little sad to hear its performance is poor. I've also found that processes like Guard which watch files for changes aren't properly notified. Even with these issues, moving all my development to VMs created by Vagrant has been incredibly useful.
