Good list - and indeed, a lot of those things I would rank as something I'd be more likely to pay for before github. Others, like DNS, you can get good services for free (everydns) unless you really need something fancy.
FWIW, Tucows DNS service is free. I pay for the domain reg's and email. They used to charge for it, like $0.25/mo or something, but then it became free. Woot.
