Yeah, Wave was a great tool for remote collaboration/project management. There's the Apache Wave bundle you can self-host, but it's not as simple as just linking someone to wave.google.com.

I was just being snarky. A router requiring you to have a Google account seems needlessly complicated. We could crank it up a notch and allow only the users of an esoteric and obsolete messaging system use it.

Wave was a cool idea, though. But refusing to integrate it with e-mail under the assumption everybody will stop using it was a tad optimistic.
