Should this clubs be able to operate standalone in case of lack of the
connection to the central hub, or is the connection to hub assumed
always present?

If the latter, you could have a jabber server installed on the hub and
just have local c2s managers deployed in each club network.
Both jabberd14 and jabberd2 work fine in this arrangement.

Every-user-sees-other-user is a common requirement for hosted chat
servers. It is usually called "shared roster" feature in jabber servers.
But keep in mind that having it makes presence exchanges grow
exponentially to the number of users online.

Maybe you could do with a autojoin-chatroom feature of a client?
Most popular Jabber clients have it implemented.
