As far as I (the author) knows, sshuttle is the only program that solves
the following common case:

 * Your client machine (or router) is Linux, FreeBSD, or MacOS.
 * You have access to a remote network via ssh.
 * You don't necessarily have admin access on the remote network.
 * The remote network has no VPN, or only stupid/complex VPN protocols
   (IPsec, PPTP, etc). Or maybe you are the admin and you just got
   frustrated with the awful state of VPN tools.
 * You don't want to create an ssh port forward for every single host/port
   on the remote network.
 * You hate openssh's port forwarding because it's randomly slow and/or
   stupid.
 * You can't use openssh's PermitTunnel feature because it's disabled by
   default on openssh servers; plus it does TCP-over-TCP, which has
   terrible performance
