Is this currently possible? Can't see anything in the docs. If not then I guess this is a feature request...
+1 This is not currently possible, but I think it should be. This would save me personally about 80$ a month, and a micro instance is more than enough to run a handful of small nodejs apps.
The only catch here is hostname based virtual hosting isn't compatible with SSL. I think that's fine.
As far as developer experience. What if you ssh'd in as ec2-user and had a 'create_app' script that your ran? then we could build a reasonable client side experience so you could attach an app to a server rather than create.
dunno when I'll have time to attack this, but solid +1 on the idea.
