    What steps will reproduce the problem?

    1. Try downloading the source code for Touchpad Pro - it isn't the most current code, and the developer has abandoned the project and closed the source under the name Teleport. See the Touchpad Pro website: http://www.touchpadpro.com/
    2. Try downloading the source code for Teleport - you can't. This app is being sold on the iTunes store for $24.99, but it was developed using GPL code as its base. See the Teleport website: http://www.jugaari.com/

    Why does this affect Chicken of the VNC?

    Teleport is based on Touchpad Pro, Touchpad Pro is based on VNsea, and VNsea is based on Chicken of the VNC. Since Teleport and Touchpad Pro violate the GPL, only copyright holders can enforce the GPL. Chicken of the VNC is a source of copyright holders that are affected.

    Additional information:

    The FSF offers assistance to copyright holders enforcing their GPL rights.

      "Teleport is based on Touchpad Pro, Touchpad Pro is based on VNsea, and VNsea is based on Chicken of the VNC... "

      How do you come to this conclusion?

        As per the VNsea website (http://code.google.com/p/vnsea/):

        "VNsea is a graphical VNC client for both the iPhone and the iPod touch based on Chicken of the VNC for Mac OS X. CotVNC is also hosted at SourceForge."

        As per the Touchpad Pro website (http://www.touchpadpro.com/2008/04/touchpad-pro-faq.html):

        "Yes, this is open source software, and it's built on another open source project called VNsea by Chris Reed and Glenn Kreisel."

        Also per the Touchpad Pro FAQ:

        "There's an app on the App Store called Teleport. Can I get a discount on that if I've bought Touchpad Pro?

        There is no way to get a discount on an iPhone application at this time. If / when that rule changes, this will definitely be explored. Unfortunately, this is simply not possible at this time. Stay tuned..."

          That's a pretty tenuous link.

      I mean no offense, but...

      - the developer of Touchpad Pro and Teleport are the same individual
      - the Touchpad Pro FAQ indicates a link by alluding to a possible discount for Touchpad Pro purchases
      - the interfaces and functionality of the two programs are identical

      ...and you believe the link between the two programs is tenuous?

      Does this mean then that you believe that the developer of Teleport wrote a GPL free rewrite of the entire application over the course of one to two months? Your alternative seems far more tenuous than my assertion.

      At any rate, it is up to the CotVNC and VNsea developers to decide if they will pursue this. If not, the developer of Teleport should make some good coin off the code CotVNC and VNsea gave away for free.
