Another Screen Share Suggestion! Showing Clicks!

I don't know if this has been suggested before, but with a quick search, I didn't notice anything remotely similar.

With that said, I bring the suggestion of enabling users who are screen sharing with one another, to be able to click each others screen share and display a temporary pointer. For any of us who have used Team Viewer, you'll know what I am referring to.

For example, let's say my buddy is screen sharing with me as I am walking him through an install or use of a program. I tell my buddy, "Click that little blue arrow in the mid left of your screen." Most of us go blind with such directions, 'What blue arrow??' With this suggestion, I could click on his screen share and it would show an arrow of my click.

This would be useful for tutorials, walk throughs. I do a lot of design work with friends and being able to say and show "Hey if you moved this up a little bit, like right about here" would be greatly beneficial. I assume a bunch of other people who also use screen share for similar things would also benefit!

So, what do you guys think? Yay or nay?!
