Deploy Windows 8 To Go through SCCM 2012 SP1

Question

First a little backgroud:
I have SCCM 2012 SP1 with MDT 2012 Update 1 integrated. I am using an MDT UDI task sequence to deploy windows 8 and it works perfectly. My Windows 8 image is fairly thin (only containing OS updates and C++ runtimes), and I am using the MDT database
and an MDT task sequence in SCCM 2012  to dynamically set a list of SCCM Applications to install as well as settings based on location. 
Now I want to get Windows To Go provisioning working in SCCM 2012 SP1. I had a powershell script that preparied the drive and applied a thick image (including office and other apps) to it then updated unattend.xml with a computer name and the domain join
info.  That worked for me however I'd like to levarage the dynamic task sequence that I described above to build these To Go sticks the same as my other Windows 8 machines without having to keep updating the thick image evertime something changes. 
There isn't much info out there that Iv'e found on setting up SCCM 2012 SP1 to provision windows to go here are the two that I have found

I followed the instructions in the first link and was able to run the Windows to Go Creator program and apply the prestaged wim to the USB stick. I rebooted from the USB stick Windows PE started and started to run my task sequence then it errored out on
the apply image step. At this point it occured to me that the MDT SCCM task sequence was probably not setup for prestaged media and or Windows To Go. 
So my question is am I on the right track? Do I just need to examine each step in my task sequence and make sure that it will work properly with my Prestaged/Windows To Go stick? If so has anyone actually gotten this to work that could give me some advice?
Or is it asking too much to have a dynamic Windows To Go task sequence and I should just be building a thick image and using a second task sequence specifically for Windows to go? 
are there any other resources for Windows To Go with SCCM that I'm missing? 
Thanks, 
Tony

First of all sorry I missed your last three posts I have to check my email notifications. I'll try to answer all of them even though I think the last part is the only one where you are still stuck. 
When I created my prestaged media I didn't put anything into it except for the the OS image and my PE image. On the Select Application and Select Package screen in the prestaged media wizard remove any application or packages that are added automatically.
The task sequence is supposed to be smart enough to know if the version of the package that is on the prestaged media is out of date and go to a DP to get it but that didnt work for me. The only way I was able to get it to work was to remove all the packages
from the prestaged media even the Customsettings package, the MDT toolkit package, USMT, etc..

This thread which is about prestaged media in SCCM 2007 helped me to understand how prestaged media is supposed to work. Basically what I learned is that once the computer is rebooted from the ToGo stick into PE the task sequence will run the same as any
other task sequence installing any applications and setting up your ToGo stick just like any other computer that runs the task sequence they dont need to be in your prestaged media for this to happen. 
You shouldn't need to worry about partitioning WTGCreator.exe will partition the ToGo stick for you I'm just using the standard MDT Integrated partitioning in my task sequence. The one thing that I did was set the Windows To Go Creator package to "run from
distribution point" which speed things up because then it didnt download the prestaged wim then apply it to the USB drive. 
Is it booting into PE then rebooting? Did you check the "Allow unattend operating system deployment" check box when you made your prestaged media? If so it wants you to have set the task sequence to run in a task sequence variable SMSTSPreferredAdvertID
to the task sequence ID you want to run. I'd just remake the media and leave that box unchecked. 
Good luck and let me know how it works for you. I'll check back sooner this time I promise.
