Who is MUC_JIDS?

Everybody on earth seems to have

MUC_JIDS=JvbBrewery@domain.example.com

My question: what is MUC_JIDS? Is this something that should be the same across all nodes of a cluster? Or is this something like MUC_NICNAME that should change from JVB to JVB?

it’s a special XMPP room where jicofo and the jvbs are meeting.

Ah cool. This is should be the same for all the JVBs in a cluster then. Thanks.
