[paramiko] copying only recent files from one machine to another.

[James Bardin]

If you're not looking to create stateful transfers, you could just 
compare the mtime of the local and remote files.

An sftp instance has stat(), and lstat() methods. These return an 
SFTPAttributes object with properties that can be compared with 
os.stat() and os.lstat().
