Working on an app that is loading "sub-applications" from a server gathering QML sources to be executed. It does this for security isolation reasons, as the sub-apps are 3rd party. The sources contain the JavaScript application logic which calls host app's API out of the QML. The logic complexity and amount of data the sub-app could potentially face is expected to increase which would obviously lower the overall performance and increase memory consumption. I'm wondering whether it's possible to dynamically load logic components written in C++ besides the QML of the sub-app for increased performance? The app is cross platform by the way.

Qt plugins are just shared objects / dynamic-link libraries with a convenience API. Don't know what exactly you're doing there, but allowing your host application to be linked against 3rd party shared objects might undermine your security concept.

@romsharkov This is fantastic. I would love to see the result of the work. I was trying to attempt something like this but never thought it would be possible. Can you put the both server and actual project files in github as an example. This is a nicest approach I saw since some time.

@ganeshkbhat Allowing to load and run 3rd C++ inside your main applications's process is very dangerous and we have not found any easy way to sandbox C++ so far, only just have a few ideas worth trying. I've described this issue here in a little more detail.
