[TYPO3-mvc] Best practice Wizard/Popup

[Felix Kopp]

Dear list,

what is the best practice approach to display Extbase/Fluid output 
within the backend - without the entry point via module/submodule?

Two cases I have in mind:

1) Create an extbase controller with fluid output that can be attached 
as a wizard to a $TCA field.
	'wizards' =>
		… 'edit' =>
			… 'script' => 'mod.php?tx_…' <- ?

2) Use extbase controller with popup/modal in backend accessible via 
toolbar or context menu.
	mod.php?


The entry point will be mod.php: What exactly is the path via 
dispatcher/Bootstrap and how to register without module/submodule?

Cheers everyone &
happy extbasing,
Felix*
