Very good resource to such a common question! Thanks for working towards this. I'm not sure how feasible it would be, but might also be interesting to have a way to compare what similar resources would costs in normal hosting/cloud providers today.
"It's estimated your usage would require ### of staked EOS tokens. At current market price that would require an investment/expense of $$$. The comparable cost for this would be approximately $$$ per year, where you pay recurring charges for consuming such resources. With EOS, you only pay more if you require more tokens to access more resources."
