We did have access (for most of the time), it's just that no one is
interested in putting in lots of hours on sysadmin duties.

That's awesome persistence. The NumPy and SciPy buildbots certainly weren't
maintained like that, half of them were offline or broken for long periods
usually.

I do see the value of testing on more platforms of course. It's just about
logistics/responsibilities. If you're saying that you'll do the
maintenance, and want to apply for resources using the NumPy name, that's
much better I think then making "the numpy devs" collectively responsible.
