Is sshfs a serious replacement for nfs? I've got a Buffalo Nas at home that I use Samba for, but Samba is too slow to watch hi-def videos over. NFS seems to be a pain in the neck to get working on that particular device, and I hate using it on a laptop. I guess I should probably just try it, but I can't see SSHFS as being any faster than Samba.
It'll probably be less performant than NFS, but is a really great and simple way for mounting remote volumes securely across the internet without having to worry about VPNs or any extra authentication or anything.
