There's a couple of missing deps (which I think is by design) in 2.0 that prevent you from being able to access networked resources (NFS, FTP, Samba, and a few others) from pcmanfm out of the box. If, like me, you're happy enough with pcmanfm and don't want to install extra software to handle this type of connectivity, then you'll find a couple of missing deps quite handy... Install them, and you will be able to connect to these resources without needing to install extra software. Doesn't even require a reboot or logging out.
Open up Terminology, and type:
sudo apt-get update && sudo apt-get install fuse-utils gvfs-backends
Give it your password, and let it install. If you prefer to install from synaptic, the package names are "fuse-utils" and "gvfs-backends". With them installed, you should be able to continue using pcmanfm to connect to networked resources. Just put the protocol type and the resource address in the location bar, for example "smb://my-server/my-share" or "ftp://user:email@example.com"
