Are you refering to the binary?

I think for users getting started that's a great idea, but at the same 
we need to provide a
"register realm" functionality, because some realms can have a lot of 
data and be located on different partitions
and hence it's not always that easy.

If we talk about the binary location, then it won't work when running it 
wihin cluster, whereas one could copy the realm.xml files, but the 
actual data would exist only once.

So I think additonally to "register realm" it would be great to have 
this :-)

how could this ant task be triggered?

yes, that would be nice, but I guess one needs to reconfigure Tomcat, right?

yes, that would be great, whereas I have no clue how to do this.

sounds good to me. Maybe we can refactor the from-scratch-realm as a 
"best practice" example

I think generally that makes a lot of sense. We only have to keep in 
mind clustering, multiple realms (and possible naming conflicts).
