It's interesting opening two tabs and only drawing on one, and using the second tab to see what other people are probably seeing.

Some strokes have huge lag during spikes, others that I made on my screen are never displayed on the other tab.

The server had a hard time dealing with the load. I suspect running node.js on Cygwin contributes negatively in that regard. Furthermore, my custom serverside canvas could probably benefit from being asynchronous, and the server really should batch up updates within a certain time frame, to not hammer other clients.
