[opencms-dev] Is asking about clustering considered rude?

I am trying to figure out why I can't get a response about how to use a
feature that is listed on your "Features" web page?  The clustering/
auto update of slave sites is a MUST have for me and its mention on the
website is the reason why I spent a week installing an playing around
with this application.  If it isn't implemented might I recommend a
patch for your website?

 <p>Running OpenCms in a J2EE application server environment (e.g. BEA
Weblogic) provides facilities for making use of distributed object
architectures, particularly with regard to Enterprise JavaBeans
technology. Using these techniques, processes behind the web site may be
structured and distributed in a component oriented way. Presentation and
business logic can be developed strictly separated, according to the
four-tier architecture described in the J2EE Application Model. OpenCms
takes care of the presentation of the data, using the integrated JSP
template engine for creating the general website layout, while the
generation of the content data is relocated to EJBs.</p>
 <a name="search"></a><h5>Search engine support</h5>
 <p>Using the OpenCms module mechanism (see <a href="#modules">Module
mechanism for extensions</a>) various full text search engines can be
plugged into OpenCms. With a full text search engine like for example
the Open Source search engine ht://dig it is possible to generate
multiple search indices for different languages and/or content areas of
a website. With additional software available as Open Source or
commercial packages, it is also possible to search document types like
PDF, MS Word or EXCEL files stored in the OpenCms content
repository.</p>
-<a name="balancing"></a><h5>Clustering for load balancing and
failover</h5>
-<p>To ensure the availability of a website even in the case of hardware
failure, or to handle websites with high load, the OpenCms installation
can be clustered on several server machines. Common hardware solutions
like for example CISCO local director are fully supported. OpenCms will
automatically update all servers in the cluster if new content is
published.</p>
 <a name="properties"></a><h5>Meta information (properties)</h5>
 <p>Various properties can be attached to every resource in the OpenCms
content repository in order to store individual meta information.
Depending on the installation, these properties can for example control
the appearance of a template, select which content channels are
displayed on a page, or provide optimized information for search
engines. The value of a property can easily be changed by the user,
provided he has the required permissions. Custom properties and
functions can easily be added, e.g. for attaching target addresses to
email forms.</p>
