I use the RME's loopback to do this sort thing. For example, recording audio for Videos where I'm combining Sonar Outputs with inputs that aren't part of the project (me talking). I record all of this in RME's DigiCheck.
 
It's a bit like having a DAW on top of DAW and it is useful.

I did not think at first it would be useful either but once you have used it then it all changes.

Yeah but I bet if you went back and offered Alan Parsons and Pink Floyd some automation for their mixing project they would've jumped at it. And continued talking about how much time they saved while at the pub drinking instead of doing take 237 of the "Money" mixdown.

Yes and they would have jumpd at it too I agree except they would have automated 90% of it and used manual control for the rest. You are thinking a bit black and white.  It does not have to be all one way or the other. Why not some of both.  Same as mixing all on an analog console or all digital ITB. What is great about today is we can have a large chunk of the mix ITB but some parts of it featuring some nice analog processing.

This feature would be nice to have and where I needed it was in my Z3ta+2 presentation. I was recording a vox track and wanted to capture the audio out from Z3ta+2 as I was tweaking. Impossible to do without a physical loopback. The potential for a positive feedback loop here is worrisome, so having the audio from a source going to a recordable audio track would be very handy (and safer to hardware involved).
 
Edit: Added link to that thread. How I completed the routing is in post #3.

SONAR has live bounce capabilities if desired.

Yes but can you make changes along the way.  I think you may find you can't.  Not sure with Sonar of course but with Studio One if I ask it to do a real time bounce it does it fine in real time except you cannot change anything or make any moves along the way.  They lock you out!  This is where the buss to track feature comes into its own because you can then.
 
 

Just select the "live input" option in the bounce dialogue.

You can't change fader settings, etc during live input bounce. Just tried it.

I wouldn't expect it to. I assumed as Jeff was referring to "analog processing" he was referring to external gear. FOr anything in the box there's always automation.

fwiw i would expect it to, as it's "live"... but it seems like it's only semi-"live"

Perception I guess then. I've always assumed "live input" to refer to anything coming in from OTB, as opposed to stuff ITB.
 
For example, I wouldn't expect to record notes clicked in the PRV note pane but I would expect notes played on one of my controllers to be recorded.
