You'd have to:

1)  Subclass Node to add more specialised behaviour, maps, locks, etc. tuned for this (InternalNode?)  Perhaps even add more specialised checks that "user" methods like get() and put() from the Node interface throw exceptions so end-users don't mess with these regions?

2)  The factory would have to instantiate the appropriate class, based on the Fqn requested.  

Changing the NodeFactory wouldn't help anyway, without 1) and 2) above, and wouldn't really add much specific benefit given how few InternalNodes would ever be created (just /_JBoss_Internal_ and /_BuddyBackup_?  I don't think sub-nodes under /_JBoss_Internal_ and /_BuddyBackup_ needs any further special behaviour?)
