Instead of Esc you can use Ctrl-C without any delay. I learned this years ago when the latency of a satellite Internet connection would interfere with Esc and Meta.

And, if you remap Caps Lock to Ctrl, Ctrl-C will be easier to type.

This works 99% of the time. The only exception I know of where it performs differently is in operations on a visual block (not visual line) selection -- hitting Ctrl-C only applies changes to the current line but Esc does what you want.

One of the tradeoffs of Heroku's great hosting solutions is that they don't support WebSockets.

If you're worried about compatibility, check out PubNub or Pusher.

Most of the work was done inside of a week with no plans to ever launch it publicly. Then we changed our mind, spent another week on it and wrote up a blog post.

The hardest part was probably the mutliplayer networking and latency compensation. It required a lot of tweaking and it's still far from perfect, but I think it's pretty reasonable for two weeks of work :)

Agreed. This is the reason I tried this tip many years ago and removed it.
