does anyone know anything briefly about this protection?

I've read all the related threads, but all of them are related to games (If I would have any time to play...) or in particular, applications that are "locked" to original CD.

but now I have a target with this Starforce "Frontline 3 Pro" envelope protection.. I dumped it quite easily, and just continuing, but I decided first to ask around. not that I don't have "Google subscription", but I have some reasons for doing this, namely:
- this is not a game or similar, not even in size, so no cd or anything, it is just an 1m app
- would be neat to analyse the protection, but obviously, no trial versions available at all.
