There's something to add to Jack right there. Make it so that every Jack user can optionally "donate" their computer time to a project.
I have a mac with Morphos I never use. (It's in storage right now, in another state, won't be able to get to it for a few months). If Jack had an option to donate the machine's time to a project, or to a general "up for grabs" project pool I'd install Jack and leave the machine plugged in and forget about it. Of course for the pool idea you'd need some kind of screening to prevent anti-social people from abusing the opportunity.
