Now it seems more like an Activity Manager. I didn't look very close to it, but I see that you extensively use cgroups to actually group the processes, i.e. 'daemons' cgroup, 'apps' cgroup. So, it might be a very good start for truly cross-platform, truly generic way to implement Activity Manager. :) I'm surely interested in how it evolves, and will take a closer look soon.
