At the moment, you need to know which PID you want to track. I have a prototype using ptrace to do something similar to strace --follow-children /path/to/executable but I only had time to do the underlying plumbing. All the user interface needs to be designed and implemented. If you are interested to look into this I could dig out my prototype branch.
