I could try to help with that, it would be an opportunity for be to
get to know software-center source-code. I'll take a look at it in the
next few days.

What about the server side? Is the OCS server ready to receive this data?

Good! In fact, I didn't know about zeitgeist at all, thank you for the tip :)
Maybe we can get more acurate data with zeitgeist, but popcon also
keeps track of package usage through filesystem's ctime and atime. And
at the same time that zeitgeist provides more information about users
activities there would also be more privacy issues to be taken into
account if we choose to use it.

I agree with you that r&r will probably provide a rich data source for
recommendations. On the other hand, I also think that popcon is
useful, and the advantage is that the data is already there. We could
try to develop both approaches in parallel, since r&r still depends on
OCS server and user sending real data to the server.

Great! Let's continuing continue this conversation.
