Can Authereum eliminate gas costs for a dApp?

[vporton]

I am not sure if this is the right repository to file this bug report. Anyway, at https://authereum.com/welcome the contact form does not work: "Failed Google Recaptcha Verification. Please try again." I tried again several times.

I want to eliminate users paying transaction gas costs (as they do with MetaMask) in my dApp.

Is it possible to do with Authereum? Can Authereum replace MetaMask for this purpose? Can Authereum be used as a MetaMask provider? Is it considered to file a pull request to MetaMask source to use Authereum as the provider?

Is Authereum stable enough for this purpose? My app is non-financial but probably significant ETH transfers may occur in it.
