Sounds good to me ... I don't know how much control you have over these things, but would it be possible to just upload to a /proc file and Hijack would look at the length of the animation file and implement the idea you were talking about (writing at the end of the kernel, etc)? If not, I would need some special code for uploading boot animations (which shouldn't be a big deal if it's a pain for you to do the proc impl).
