(Apologies for cross-posting).
matplotlib has a dire need to improve its continuous integration testing. I've drafted MEP19 and solicited comments, but there hasn't been a lot of feedback thus far.
As an alternative to mailing list discussion, where this sort of upfront planning can sometimes be difficult, I'm considering holding a Google Hangout in the next few weeks on the subject. It's ok to participate even if you don't have the time to work on matplotlib -- I would also like feedback from advice from those that have configured similar systems for other projects. matplotlib's needs are somewhat more complex in terms of dependencies, cpu, ram and storage, so we're pushing things pretty far here.
If there's enough people with an interest in participating in the discussion, I'll send around a Doodle poll to find a good time.
