Awesome, following the directions, it took just a few minutes to get a local copy running. I used to run my own online word processor, written about 6 years ago for my own use, but a few thousand people signed up to try it. It is tempting to run an EtherPad instance for my business clients, and another one for my friends and family. That said, eventually I think that Wave will be awesome so sticking to that makes the most sense. Investing a lot of time to get into the EtherPad codebase seems like a slippery slope to non-productivity.
