The sendmail solution (kludge? at least on Linux :) requires write access to /dev/kmem which only root can do. It would be a lot cleaner if you could indeed modify the cmdline via the /proc filesystem. I really like the idea, especially when programming with threads; ps should be more useful if you could easily "rename" threads without root privileges. It sure beats seeing 20 ps entries with the original command line..
