The user experience that has contributed to Snapchat's success is the ability to message with untrusted partner with constraints established by the central server and client. The biggest constraint is certain level of inconvenience in logging and redistributing the contents of the conversation. Snapchat's business value could evaporate if clients that subvert the constraints on the user experience proliferated. The discussion seems to indicate that the technical barriers to this outcome are deeply inadequate. Snapchat looks like they are primarily going to use mechanisms to block the distribution channels of the Play Store and iTunes to ensure user experience integrity. This has the potential to fail catastrophically.
