Heroku (and others that I haven't tried) solve this well, but they are expensive if you run a large site. If I know that I want an obvious setup such as a reverse proxy + load balancer + multiple rails (or other) servers + a master/slave db setup on linode/slicehost/MT to save server costs, but do not want to do the sysadmin work, and maybe do not know enough about security etc......then OP's tool seems quite useful for me. Ideally, I would like an interface that takes in parameters like the above, and generates scripts (such as stackscripts, or some similar alternative), that would just run and configure the systems. Or in other words, give me a Heroku like interface to configure Linode/MT/slicehost :) I would be willing to pay a reasonable upfront fee for it, though the price should obviously depend on the complexity of the configuration. I would also be willing to pay for monthly support. From a developer's perspective, I think this is basically outsourcing the sysadmin work which most people don't seem to want to do/learn, even though they realize how important it is for their site.
