That's basically a hello world project. As you found out, the hard part is everything else, like funding it.
Honestly half of why I took it down is nobody was really using it. I didn't work terribly hard to market it, as I had no aspirations of getting rich and it would've been tenuous to monetize at all. I just told friends about it, etc.
I didn't imply there was a "hard part" to it. Just a neat idea. No need to dump on it.
About 15 years ago, my sites were pushing 400-600mb/s non stop. Nowadays, I barely hit 1% of my network cap at each VPS location.
