Hi Greg;
Heino is correct, Appeon will not be providing a public beta program for PB 2017. One of the main reason is that the product would need the new active licensing feature to be incorporated into the early releases first - which is one reason that offering the beta program is very difficult for us in this 1st Appeon PB release. This will not be a large issue in subsequent releases.
Appeon is planning to have public beta's for PB 2018, 2019, etc.

AFAIK, yes there will be a trial version. However, there has been no official information released on this aspect as of yet. My guess, is that this version would be available after PB 2017 GA ships.
