Yikes. That'd involve moving a lot of control path machinery into the kernel, particularly for the v6 side where "release" isn't just a shot-in-the-dark datagram. Before designing some detailed solution like that, I'd like to see a project that investigates how this stuff *should* work and looks at the range of possible solutions. I don't know whether what you're suggesting is necessarily part of the answer.
