It's funny you bring this up because I was just reading this [1] interview and there is a section where Jens talks about the recently added kernel syscalls for doing splice/tee without the overhead of extra copies of the traditional tee. I haven't had a chance to try it out but if you have a recent kernel, it might be cool to play with. It also looks the userland utils are pretty new and will probably need to be built from source using the git repo listed in that article.
