Sure, nice kick off.

Would be great, what exactly do you want to visualize? For me, even having green/red spots
works fine in order to quickly identify what builds are wrong.

Hopefully both. I'm attaching my config file (probably more for inspiration that a real use).
I'll ask my manager whether we can find a machine that can run more complex tests. I'll inform you.

Yes, duplication in way that it is (will be) same things. I'm adding author of the tool,
hopefully we can unify the effort (and resources of course).
