Hello So pginfra had a little chat about this. Firstly, there's consensus that it makes sense for pginfra to help out with some persistent workers in our existing VM system; however there are some aspects that need some further discussion, to avoid destabilizing the rest of the infrastructure. We're looking into it and we'll let you know.
Hosting a couple of Mac Minis is definitely a possibility, if some entity like SPI buys them. Let's take this off-list to arrange the details. Regards -- Álvaro Herrera
