I carry an HDMI cable with me to meetings and show the phone on an overhead projector. Although you don't have the benefit of seeing your fingers, it's a readable and digital solution.

In the developer options on Android theres a setting "show touches", though I'm not sure if that'd show up on an external display or only the device...

yeah, but that's still different, especially when you want to show something like shaking the phone, or switching devices.
