[SailfishDevel] Jolla Harbour and Jolla Store

Well. As Harmattan havent copy protection at all, developers started 
creating own methods for detecting if application is *really* bought by 
user. And it was done using osa binaries. You can always get application 
source, and if it osa - application installed from Store (means paid 
applicatioin was bought).

I see following:

Lightweight library provides methods for developer to detect if 
application installed from Harbour (bought actually) or not. Daemon side 
of library handles this calls and send negative results to Harbour 
servers. This protection library should provide also some kind of 
*sandbox*. Functions, included into sandbox will be executed in safe 
threads and will be self-obfuscated and protected from modifications. 
Any byte changing *sandbox* part of application cause showing warning 
screen when application starting, application became misbehave or 
quiting after some period of time, and sending information to Harbour 
servers.

And developer can choose which strategy application will use: easy or 
hard, or make own methods based on easy *is bought?* checks.

> It doesn't mean that.  It will be lightweight, does not limit resources and does not care what mode you are on. People will just have to wait for untill its ready before more datails will be available. But feel free to give suggestions what kind of API's you would prefer to have as a developer in Harbour to make your life easier.
