Q:

Heroku-like services for Scala?

I love Heroku but I would prefer to develop in Scala rather than Ruby on Rails.
Does anyone know of any services like Heroku that work with Scala?
UPDATE: Heroku now officially supports Scala - see answers below for links

A:

As of October 3rd 2011, Heroku officially supports Scala, Akka and sbt.

Check out Amazon Elastic Beanstalk.

To deploy Java applications using
  Elastic Beanstalk, you simply:

Create your application as you
  normally would using any editor or IDE
  (e.g. Eclipse). 
Package your
  deployable code into a standard Java
  Web Application Archive (WAR file).
Upload your WAR file to Elastic
  Beanstalk using the AWS Management
  Console, the AWS Toolkit for Eclipse,
  the web service APIs, or the Command
  Line Tools. 
Deploy your application.
  Behind the scenes, Elastic Beanstalk
  handles the provisioning of a load
  balancer and the deployment of your
  WAR file to one or more EC2 instances
  running the Apache Tomcat application
  server. 
Within a few minutes you will
  be able to access your application at
  a customized URL (e.g.
  http://myapp.elasticbeanstalk.com/).

Once an application is running,
  Elastic Beanstalk provides several
  management features such as:

Easily deploy new application versions
  to running environments (or rollback
  to a previous version). 
Access
  built-in CloudWatch monitoring metrics
  such as average CPU utilization,
  request count, and average latency.
Receive e-mail notifications through
  Amazon Simple Notification Service
  when application health changes or
  application servers are added or
  removed. 
Access Tomcat server log
  files without needing to login to the
  application servers. 
Quickly restart
  the application servers on all EC2
  instances with a single command.

Another strong contender is Cloud Foundry.   One of the nice features of Cloud Foundry is the ability to have a local version of "the cloud" running on your laptop so you can deploy and test offline.
