How do I Show my mouse cursor to a peer (multiplayer)?

I have a multiplayer app (drag n drop stuf for classes online)

What i need, and totaly lost, is how to show to the peer (I´m always Host) my mouse position, like a laser pointer in a presentation.

I tried so far, events to "key press move a red sprite dot to my mouse.X and mouse.Y, and the object red dot is synced with multiplayer, but not working.

Is there a easy way to show my mouse position to a peer?
