Dongle yes or no, it doesn't matter for me.
But I don't want to buy a dongle for just trying a demo.
I have very good limiters and what happens if Xenon ($249 is a lot of money for just a limiter) doesn't fit my needs
or can't beat my current favourite limiter: The money for dongle is wasted !?
At least consider to release a demo that doesn't require a dongle.
