If I might make one suggestion. Whether you decide to GOUT sync or not, if you want credit for your work it might be best to do as Harmy did on his releases and put your credit at the end of the film. I suggest this since anyone who would want to mix in their preference of the plethora of audio and subtitle options out there to your footage would either have to offset or modify everything they add or, more likely, do as the current 720p GOUT synced copy on the spleen did and remove your credit at the beginning of the film. I added hairy_hen’s DTS-HD MA 5.1 track quite simply to that 720p GOUT synced version, and the result was glorious, even despite the occasional missing frame placeholders, and is about how I think I would preserve and distribute this with respect to your final version; it would be regrettable having to do so without credit to you.
I think this is a good idea for mkv releases. But for the BD ISO, they can just have their credit reel in a separate m2ts container, regardless of which way they choose to go (or have it show before the menu, etc).
This can be done with an mkv as well.
