I was checking out the openSUSE 11.0 Gnome LiveCD to gather some information about a Mono bug, and accidentally discovered gvfs.
I guess it's a replacement for gnome-vfs. From a quick glance, nautilus seems pretty much the same to me as when it used gnome-vfs. But, low and behold, when I opened up an sftp:// uri in nautilus, that 'share' was available via fuse in /home/linux/.gvfs!!! How cool is that??
This is probably old news, but I'm pretty excited about this. I guess there'll also be a kio interface. It seems gvfs has some really great potential to bridge the vfs gap.
