I am going to look into this, since I'm responsible for the script that puts the CVS logs into the forums.
The problem is taht I didn't realize when I wrote the script, that you have to explicitly call some notifications:: functions to generate the mail.
Now that I know that, I have to figure out a way to call these functions from a non-OpenACS/AOLserver script. My script can get away with putting things into the forums because forums has a PL/pgSQL API, so I just connect to the database and use that API.
No such PL/pgSQL API exists for notifications, which means that I'll have to write it. That's why it has taken some time.
