This is more like a question.
Nowadays git cannot handle pairing the right way, instead what is done today is: we change the email before the commit is made to person1+person2@email.com. This way we cannot display a correct image for the pair in the wall.
PS: what people actually do is: hack that into Gravatar and create an association with each pair email. That's not viable while working on a big company and pairing with a lot of different people.
It would be awesome if drone wall could get the author email, split it by "+", and be able to get an image for each person of that particular commit. Of course this could be a option that could be turned on and off. But in theory it seems simple to be implemented.
What do you guys think?
