Sharity-Light for Linux is derived from smbfs, but runs as a user level program, not in the kernel. It is roughly the opposite of Samba since it's a client for the Lanmanager protocol. Sharity-Light lets you mount drives exported by Windows (f.Workgroups/95/NT), Lan Manager, OS/2 etc. on Unix machines. The former name of this application was "rumba".
pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
