I might have just enough linux-skills for a bare minimum node, but my health-problems won't enable me to guarantee 100% uptime and quick reaction in case of problems.
Maybe some pooled effort and funds (if initially costs are higher than profits) could be organized and pay for things like Amazon cloud servers, or community nodes like mining pools, with a small team of sys-admins to keep the nodes up and running. Personally I'd only be able to have a relatively low bandwith linux-pc running at home, I don't have access to fibre-optics internet at my current residence.
