Variables are too volitile so store your PID in a file. There are several examples of this in UNIX. In Solaris the whole /proc file system.

Also put some tight permissions on the file, like 600, and store it in a working directory hard coded in the script.

This is a far from trivial task. Sending a signal to a process is easy but how that process responds to that signal is entirely up to that application -- it might be coded to ignore the signal, for example. Moreover, killing one process in a group of interdependent processes can certainly have unexpected consequences. Your problem is going to have to be much better defined before you simply start sending kill -s 15's (or whatever) to a bunch of processes.
