 1. Are you saying: Any time a widget gets focus, Orca would

I am saying something along these lines however I can't preciselly 
define it. When widget gets focus orca should check its role, states and 
ancestors in order to find out if the control is interactive and if yes 
then it should give control to gecko. If you need more details I can 
look it up in the NVDA's source code or at least point a place where 
exactly to look into inside it. I think IA2 roles are close enough to 
ATK roles so we might be able to borrow some bits and pieces from it.
 2. Are you saying there would be a single keyboard command a user 
would press to return all control back over to Orca? (Yes or no.)
Yes exactly. That keystroke would toggle the two modes no mather wich of 
these is active. Imagine it like a global switch with two states gecko 
vs orca and you can toggle between the two whenever you wish.
3. What does NVDA call each of these modes?
While NVDA does nothing and just reports accessibility related events it 
calls it focus mode. When NVDA handles the input and preprocesses 
content on its own in order to flatten it for the easier presentation it 
calls it browse mode.

4. What keystroke(s) does NVDA use for this behavior?
NVDA uses NVDA+space to toggle among these modes. By default NVDA does 
not allow browse mode within aria apps (aria-role=application) however 
it allows forcing browse mode in this scenario by providing a keystroke 
ctrl+NVDA+space. Additionally ctrl+NVDA+space can be used in other 
contexts for example while browsing embedded objects such as java 
applets or flash movies using browse mode you can jump to the parent 
document by pressing NVDA+ctrl+spacebar. NVDA key is either insert, 
capslock or numpad insert depending on the user's choice.
5. What message(s) does NVDA speak for this behavior?
NVDA by default plays a beep when toggles this no mather whether it's 
being toggled as a result of a keystroke or whether it's toggled 
automatically. There are two different sounds one coresponding with 
focus mode the other coresponding with browse mode. If beeps are turned 
off from within browse mode settings window it says either browse mode 
or focus mode depending which mode has just got activated either no 
mather whether it was activated manually by pressing the designated 
shortcut key or activated automatically.
 Again, let's first come up with a simple, clear specification. Once we 
have that, lengthy discussions can resume while I look at implementing it.

Yes I understand. Feel free to ask if you need more details. I can also 
try clarifying stuff in other words if I haven't explained it verry well.

Thanks and greetings

Peter
