Please take a look.

Description:
ProxyCommand support for go.crypto/ssh client

Implement support for the ProxyCommand option
in the go.crypto/ssh-based client. This is just
a matter of executing the provided command, and
using the process' stdin/stdout to form a
net.Conn on which the SSH session is created.
