Last year an intern made a prototype which could restart userland, which would allow patches to be put into effect without POSTing. It wasn't product-ready and I don't recall it being discussed outside of Sun. It wouldn't allow for kernel patches anyway. For those the only thing I can think of is a paper I saw at Usenix a few years ago. It might have been from IBM. David
