Possibility to commit from 'all' systems

I just started with subversion. In /etc/sysconfig/svnserve it states:
    ## Path: Network/Subversion/svnserve
    ## Description: Basic configuration for svnserve
    ## Type: string
    ## Default "-d -R -r /srv/svn/repos"
    #
    # default options for the svnserve process
    # it is recommended to provide only readonly access to your data.
    # there is no authentication possible, everyone can read and write at will
    # read the subversion documentation about more info
    #
    SVNSERVE_OPTIONS="-d -r /srv/svn/repos"

But this means that I can only make changes on the system svnserve is
running on. Is there a safe way to have the possibility to change the
files on 'all' systems?
