If someone has locked the file, no one else will be able to commit it.
Changing the read-only property of the file in the working copy does not
circumvent this.

No, I believe locking a file prevents other people from committing changes
(regardless of the needs-lock property). The needs-lock property serves to
communicate the team policy.

Agreed.

Another possibility is to make changes in the auto-props section of the
Subversion configuration file on each PC. There you can specify that files
with certain extensions will have the needs-lock property set whenever they
are added to Subversion. The drawback here is that it has to be done on
each client.
