Yep git rocks and I think yours is a useful recipe. For my needs I prefer herokugarden to running my own server. Cname with them was a snap plus everything is free and if the need arises I can upgrade to heroku (rejiggered, currently in private beta). One thing that had me concerned at first was that I'd be stuck with a banner ad at the bottom of every page - but that's just their config/.yml scaffolding. Also their text editor is beautiful but I find I don't use it, for me TextMate and git gitter done. Their post yesterday on the future of deployment I thought was prescient:
