Any way to REALLY hide tray/notification icons?
===

I need to hide individual icons in the notification area of Windows 7.  (I call it the systray for convenience.)

I know the systray "Customize" method, and that's not enough because hidden icons still show up in one click.  This is a security and privacy issue as several people use my PC.  I need the icon to just not be there.

I also know the registry tweak to hide the systray completely and that isn't an option.

And, I've tried a few free programs that boast this feature, but every one has failed to even detect the contents of the systray.

I have coding skills and I'm not scared of getting registry dirty, but I've been looking for an answer for a long time and all I've ever found is forum threads posing the same plea, but with flippant and lazy replies like "use the customize thing" and "why would you want to do that?", by people who only super-skimmed the original post.  You know what the internet is like.

Well, I heard this place is somewhere to trust for answers.  Anyone ever come accross anything I can bodge in to a solution?  Thanks a lot.
