Multiple applications (e.g. war files) on a single instance of Beanstalk

To be conservative in terms of resources (and costs), I would like to place more than one war file (representing different applications) on one instance of beanstalk EC2.

I would like you to have a appl application to map myapp.elasticbeanstalk.com/applA using warA and binding B to myapp.elasticbeanstalk.com/applB using warB

But the console allows you to load one and only war for any instance.

1) So, I understand that this is not possible with the current interface. I'm right?

2) Although is it possible to do this using "non-standard" methods: load warA through the interface and copy / update warB to / tomcat6 / webapps via ssh, ftp, etc.

3) C (2) I am concerned that B will be lost every time the BT health check decides to end the instance (e.g. consecutive failed checks) and restart the new one. Then I would have to make warB part of my customized AMI used by applA, and create a new version of this AMI every time I update warB

Please help me
