Steps to take:
Create a new ARA collection. You can choose between:
-Cloud based: Create and manage RemoteApp collections running in Windows Azure.
-Hybrid based: Create a hybrid deployment of RemoteApp that uses VNet to connect to your on-premise infrastructure.
The virtual machine template created earlier must be available now.
Check the Roadmap too:

And remember: with added value like the "Ability to publish individual applications to specific users" it will be even better :-)
