IRSee now has an "Encrypted" white board.
Available at the LFReD rebsite (may require a reload) or below.
Special thanks to Mr. Kamp for the canvas.r pane.
In theory, the "L" load button on the whiteboard canvas should start a loop that
continuously refreshes the drawing, but it doesn't. Requires hitting the "L" button
again and again.
Any ideas?
