This is an interesting question, and the major issue I see here is that the user's computer will hang if we do use it.

So, the best method may be to have something like what a lot of softwares do: "Would you like to send usage statistics to the owner to make the software better"

And then in the next release use the information to create a training set which is more comprehensive.

Note that a lot of times a larger training set can make the learning agent worse. Basically depends on where you wan the hyper plane to be drawn, etc. So, the training set *needs* to be well curated.

I think that could add value and allow us to tweak params on a way bigger database (user experience) and file formats than just ours.
So we should formulate questions we want to answer and then think about what stats we have to store in order to do so. All must be anonymized.

Indeed that is an important point. Just adding a lot of noise makes it worse. The dataset has to suit the data.
The knowledge about persons appearing in data and using that for training might be appropriate for a face matcher, like http://docs.opencv.org/master/dc/dc3/tutorial_py_matcher.html#gsc.tab=0
