Tried this years ago over dialup with some MS app. The technology was flakey and kept getting in the way. This works great.

Earlier quoted context omitted.
The drawing is basically a list of strokes, and a stroke is a list of points - that is, (x, y) coordinates. So the database is mostly a huge table of (x,y) coordinates. Uploading the entire canvas would far too inefficient - I simply upload the points. The transfer between two clients uses a technique called 'long polling'. That is, the client sends an HTTP request to the server, and the server doesn't respond until…
Did you end up using any libraries for the communication, such as socket.io? ( http://socket.io/ )
It think you're on the right path positioning this for use in schools. That's our main use case too, replacing overhead projectors in the classroom, and ruining snow days for an entire generation of kids.
Good luck!

I love it - works perfectly... but immediately the feature creeper in me has kicked in. Killer features 1. Be able to type in text (any font will do) 2. Drag-and-drop an image to be be able to annotate it over the top (would be excellent design task, e.g. using screenshots of some work-in-progress). 3. Movable objects?
In addition, basic shapes like line/rectangle/circle would be welcomed (I am terrible at drawing a circle with a mouse).
There's one thing stopping me from using it: the URL
I use jotwithme right now, and I can set a session name, then tell people to go there. Here, I have to get the url from my ipad, sent it to myself somehow, and send it to the student.
That's not exactly hard, but it's annoying enough compared to jotwithme that I'd keep using that. But if you had that feature, I'd switch. Jot's erase feature isn't as good.
I'm the author of a similar tool, https://awwapp.com/ , which is bitmap-based, ie the eraser works as it'd on a physical whiteboard, and there's no zoom (or undo/redo).
Great start, looking forward to seeing the future progress!
