I know nodejitsu has some stuff along those lines, but I don't think its anywhere near as convenient as my image.
I also think, although I would have to check, that Linode probably has some kind of N_deJS stackscripts that someone made. Again, I doubt that it is as fully configured or as convenient as my service, and that will cost you almost twice as much, since Linode only has 512MB instances (which for many sites and applications I think is way more than you need with N_de) which cost $19.95/mo. Also that won't give you any kind of DNS setup which I am doing for you just by typing the machine name in (probably not a big deal for a lot of people but it does make it simpler).
Also, I am actually hoping people who know their way around a shell terminal _will_ want this. The idea is to avoid always having to build Node and configure Nginx and reassign ssh and some things that you really don't need/want to do from scratch every time unless you feel like you need to prove you know how or something.
