"nice" seems to be doing quite nicely :-)
To me this capping functionality is a similar functionality to that provided by "nice" and all that's needed to make it useful is a command (similar to "nice") that runs tasks with caps applied. To that end I've written a small script (attached) that does this. As this is something that a user might like to combine with "nice" the command has an option for setting "nice" as well as caps.
Usage: withcap [options] command [arguments ...] withcap -h Options: [-c <CPU rate soft cap>] [-C <CPU rate hard cap>] [-n <nice value>]
-c Set CPU usage rate soft cap -C Set CPU usage rate hard cap -n Set nice value -h Display this help
