[hpsdr] Demo / Simulation Mode?

[Ken N9VV (Win-7/64)]

Thanks Warren,
all understood. The new Ethernet protocol certainly is an enormous 
undertaking. It is easy to understand that other priorities are set 
aside while this exciting work is undertaken.

However, it does make "show-and-tell" of the OpenHPSDR project difficult 
to demonstrate at Ham club meetings or Hamfests :-)

We all want to reach a large Ham community to promote the *amazing* 
OpenHPSDR activities and to *attract* more Programmers and Engineers :-)
Perhaps playback feature can be included in your plans for next year.

thank you Warren for your important feedback,
all the best to the Development Team with the ambitious new protocol,
