In that case, you migth find the users list useful too.

I'd like to know if it is possible to have 2 web/application/MMBase servers
connect to 1 database? The idea is to have two identical websites, but on
different machines. The editors should be used on only 1 server, but changes
should be visible on both servers.

Yes, that is possible.
You can use a feature called 'MultiCast' to make two webservers, who share a database, synchronise their changes.
Configure both webservers to use the same databse (in jdbc.xml, see the comments in that file for more info). You can then configure them to use multicast (see the multicast option in the mmbaseroot.xml file, should have more info).
This will make them aware of each other, and allows them to exchange information regarding changes. I believe they do need to be in the same network though.

If it is possible to do this, would it be possible to make the DB-connection
for the "slave" MMBase server read-only?

I don't think you have that option on the database level, but you could configure the security of the MMBase system in such a way that it disallows edits.
