Development, Staging, and Deploying Plugin

So DeployMint looks like an awesome plugin but it doesn't seem to work for shared hosting. (At least not for me, I have no access to mysqldump). I'm submitting a feature request for you all to develop the world's best staging plugin. One that allows the developer to mirror their mainsite (at least, maybe a template as well if using New Blog Templates), test code changes, then deploy when ready.

Anyone interested in this?

Is this something the amazing programmers here at WPMU Dev would be interested in adding to the repository?
