As I understand it, the kernel patch does group by TTY. Personally I think that's just one way of doing it and there could be others. So it's more proof- of-concept than TheOneTrueWay(tm) The config and bash commands method from RedHat does things slightly differently. Prevailing opinion on /. is that the patch method is cleaner but more restrictive, which the userspace method is more configurable but requires root. Perhaps distros will pick up on this and offer other criteria, maybe something like a profile selectable at boot-time or maybe even runtime. What *I* would like to see is flash goes into it's own group and gets throttled. Everything else running under KDE is in a different group and left to run full speed -- alan dot mckinnon at gmail dot com
