title: SFTP Client with source for ipv6
body: <p>I currently use TFTPCLIENT by Xavier Cirac at  <a href="http://www.waveflow.com/vcl.htm" rel="nofollow">http://www.waveflow.com/vcl.htm</a> . 
  I have made significant modifications to the source to add some special commands for the mainframe class computer(HP NonStop or Tandem) that is the FTP server.</p>
  
  <p>I now need to add IPv6 and SFTP capability and that does not seem to be a possibility with my current component.</p>
  
  <p>Does anyone know of any Delphi component with source that I can use.</p>
  
  <p>Free or shareware would be nice but I need it enough I will pay for a retail version if needed.</p>
