Ideal Node.js hosting service — 

1. Here’s the URL of a GIT repo, containing a Node app. Run it with forever. 
2. I want to be able to do a tail -f on the log so I can see what’s going on. 
3. And to view its file system, perhaps through a browser-based JS app.

I think that's about it. I give you a URL, you run it.

I know some services get close, but I don't want close. I want just this. 

A Node virtual machine.
