Lets face it; deploying Ruby applications is not the easiest thing to deal with. It's great if you use Heroku, or you have one or two apps on one server. But what happens when you want to run multiple apps, servers and Ruby versions.

There's not a great amount of support for deb/rpms, and RVM essentially builds from source.

@mattwillsh has offered to come and discuss the issue with us, so should make for some heated debates!
