One interesting thing that twiddling keeps in mind is a better user experience with command line like tool. It is aimed to create a concise and responsive text-based terminal for an experienced JBoss user who may not like the rich UI such as JON but are eager to have advanced JBoss service access capability.
with fresh you get real console features, that means you have piping of data streams.
For instance you could have an executable that would dump output as XML and then just pipe it trought another one to display it in console readable format.
We allready have some commands like that implemented so it would be trivial to add some more to support your needs.
As for integration with AS goes for now we have commands to interact with mbean server (list, executed,...) and with MC but this are currently at basic level.
Currently we are focused on redesigning the way new executables are written and adding tighter integration with MC which would give us better control/integration with all components that run inside Jboss AS
