Excellent!

I've been working on updating belaban/jgroups [1] to run on EC2 as 
docker containers. I also ported NATIVE_S3_PING [2] to use JGroups 4, 
and will actually use it in the AWS config.

This should allow the JGroups docker container to run on either bridged 
or host networks, using the same configuration (aws.xml). All you need 
to have is the permissions to create/delete buckets and read/write 
bucket objects.

This is only needed when starting multiple JGroups channels inside the 
same docker container *or* when you have other services occupying ports. 
E.g. if port 7800 is taken, JGroups will try port 7801 and so on.
