Other PaaS such as Heroku or OpenShift allows you to set up a custom app. For example, you can create your own app type in Heroku's cedar stack with buildpacks, or the DIY app in OpenShift with supports for hooks.
Erlang probably isn't on the top of the priorities list, but I'm looking forwards to it.
Other than those, it's a very good PaaS.
I love Trello, but it's supposed to be generic, and thus, not easy to use it as a Kanban board (limit number of cards per list, etc) out of the box.
