Is it possible for non-owners of a kernel.org account to do this?

Well, .git/objects for your kernel still consumes 121M. It's not gigabytes but I still wouldn't want too many copies of that lying around. Right now, I already feel slightly motivated to move the whole content-addressable idea into the kernel. It has disadvantages, but the effect on disk- and pagecache-footprint for people like me would come in handy.
