Unfortunately no, this is not a technical possibility.
We looked at many methods for Add-on installation and security, including USB keys and online authentication, as well as time-based demos.
The method we use now with the unique DNA and Add-ons where a specific unit is upgraded (forever, and it’s value increased) was decided to be the most secure and reliable.
For example, a key could be lost, stolen or broken just before a show, secure USB keys are very expensive ($100+), time limited demos are not possible without a clock (which the SQ does not have) and would be at risk of hacking, counting boot cycles would mean that some people would just leave their consoles on 24/7…
For companies or institutions with multiple consoles, we instead offer a discounted rate when purchasing the same add-ons for all.
Thanks,
Keith.
