Wasn't Wave the cloud service that promised to be a federated application, but delivered the open source server very late (like after the failure/shutdown was announced)?

Comparing anything that is not federated with Wave sounds odd to me.

Wave was federated? First i've heard of this. Where can i find this OSS server?

Also, federated seems like the least important wave feature that people talk about.

At the time federation was not that special. E-Mail was federated and Jabber/XMPP was federated too. So it was expected, that the successor (as which Wave was marketed) of e-mail was federated too.

The real time aspects, on the other hand, were pretty amazing at the time. From todays perspective the reverse might be true ;-)

The underlying architecture was federated; basically an XMPP extension. When Wave shut down, they handed the federated server code to the Apache Foundation, who briefly developed it under the name "Apache Wave". Apache Wave was shut down in 2018, but you can still download the code.
