Honestly I don't think so. I don't think taping a CD to a laptop is perfect, but you can imagine all the technical difficulties that come from using something like a Wacom tablet like home, right? Drivers/software/OS support for the tablet? What program do they use to write in? How do they share that with attendees? How reliable is all this? There's a simplicity to keeping it completely analogue which has much less failure scenarios. I don't have a link, but a saw a tweet where a teacher (?) had 3D printed a mount for a mirror to put on the laptop lid, a more polished version of this same thing, basically an overhead projector for a webcam.
