Hey gesser,

You can put two modules into one with your manifest (.dnn) file by using two "folder" elements.

Example:

<dotnetnuke version="3.0" type="Module">
    <folders>
        <folder>
            <name>Engage: Example</name>
            <friendlyname>Engage: Example</friendlyname>
            <foldername>EngageExample</foldername>
            <modulename>Engage: Example</modulename>
            <description>An Example module from Engage Software (www.engagemodules.com).</description>
            <version>01.00.00</version>
            <businesscontrollerclass>Engage.Dnn.Example.FeaturesController</businesscontrollerclass>
            <dependencies>System.Web.UI.ScriptManager</dependencies>
            <resourcefile>Resources.zip</resourcefile>
            <modules>
                <module>
                    <friendlyname>Engage: Example</friendlyname>
                    <cachetime>0</cachetime>
                    <controls>
                        <control>
                            <src>DesktopModules/EngageExample/Example.ascx</src>
                            <type>View</type>
                            <supportspartialrendering>true</supportspartialrendering>
              <helpurl>http://www.engagemodules.com/Support.aspx</helpurl>
                        </control>
                    </controls>
                </module>
            </modules>
            <files>
                <file>
                    <name>EngageExample.dll</name>
                </file>
      </files>
        </folder>
    <folder>
      <name>Engage: Example2</name>
      <friendlyname>Engage: Example2</friendlyname>
      <foldername>EngageExample2</foldername>
      <modulename>Engage: Example2</modulename>
      <description>An Example2 module from Engage Software (www.engagemodules.com).</description>
      <version>01.00.00</version>
      <businesscontrollerclass>Engage.Dnn.Example2.FeaturesController</businesscontrollerclass>
      <dependencies>System.Web.UI.ScriptManager</dependencies>
      <resourcefile>Resources.zip</resourcefile>
      <modules>
        <module>
          <friendlyname>Engage: Example2</friendlyname>
          <cachetime>0</cachetime>
          <controls>
            <control>
              <src>DesktopModules/EngageExample/Example2.ascx</src>
              <type>View</type>
              <supportspartialrendering>true</supportspartialrendering>
              <helpurl>http://www.engagemodules.com/Support.aspx</helpurl>
            </control>
          </controls>
        </module>
      </modules>
      <files>
        <file>
          <name>EngageExample2.dll</name>
        </file>
      </files>
    </folder>
    </folders>
</dotnetnuke>

Hope that helps!

Take care,
