It doesn't replace the traditional keyserver, it merely simplifies the process of keeping up to date public keys of members of your organization (or an organization that you follow). It also allows you to keep every member of your group up to date when new people are on-boarded with the new users pubkey.

Just as a keyserver for your org would?

But without the overhead and headache of running your own keyserver.

This is really awesome! Excited to use it.
