Password Protected Site Development

I would like the ability to build and test my site directly on the server that it will be installed on while that site remains password protected.

Currently developing for multiple domains, all are hosted and have a control panel directory lock preventing indexing or public access.

Providing the server name / password combination in Blocs - Projects Settings, would allow for direct previewing of the live site without having to install a local server on the local machine.

Is this something we can look forward to?
