No.

Yes.

The mechanism you're referring to is jboss-structure.xml.
* http://www.jboss.org/community/docs/DOC-13178
Even if you use this mechanism, we still need to read into the jar, its 
META-INF.

Actually, in MC/AS you never use anything else than VFS to navigate/read 
some stuff in file system.
If you do, it's bad/wrong usage. Since that's why we wrote VFS. ;-)
