Creating a Daemon based sftp client

Question

If i were to build an sftp client which launched with logon details, and could then controlled by sending commands to that daemon; would that be ideal way to create an sftp client with disposable credentials?

Answer 1

I believe such clients already exist:

• sshfs

  sshfs host:path ~/mnt
  

• SFTP modules for GNOME's GVFS and KDE's Kio

  gvfs-mount sftp://host/path
  

All of these run as daemons and are controllable through standard operating system functions (read directory, open file, etc.).
