Hi Jeremy, all, Sorry this took so long, spent last week in Japan at OSDL conf then netconf. After several false starts, I ended up with a very simple implementation, which clashes significantly with your work since then 8(. I've pushed the patches anyway, but it's going to be significant work for me to re-merge them, so I wanted your feedback first. The first patch simply changes
