Sure. ;-)

I've written two examples (they are commited to the trunk) 
of what you can do to enable this:

(1) annotation based

  | <deployment xmlns="urn:jboss:bean-deployer:2.0">
  | 
  |   <bean name="AnnotationHandlerFactory">
  |      <constructor factoryClass="org.jboss.kernel.plugins.annotations.BeanAnnotationAdapterFactory" factoryMethod="getInstance" />
  |   </bean>
  |   <bean name="AnnotationHandler">
  |      <constructor factoryMethod="getBeanAnnotationAdapter">
  |         <factory bean="AnnotationHandlerFactory"/>
  |      </constructor>
  |      <incallback method="addAnnotationPlugin" />
  |      <uncallback method="removeAnnotationPlugin" />
  |   </bean>
  |   <bean name="SuperDemandAnnotationPlugin" class="org.jboss.test.kernel.deployment.support.SuperDemandAnnotationPlugin" />
  | 
  |   <bean name="Manager" class="org.jboss.test.kernel.deployment.support.SomeCacheTreeManager">
  |     <property name="clusteredCache"><inject bean="HAPartitionCacheHandler" property="cache"/></property>
  |     <annotation>@org.jboss.test.kernel.deployment.support.SuperDemand(demand="Partition", whenRequired="Configured", dependentState="Start")</annotation>
  |   </bean>
  | 
  |   <bean name="HAPartitionCacheHandler" class="org.jboss.test.kernel.deployment.support.HAPartitionCacheHandler"/>
  | 
  |   <bean name="Partition" class="org.jboss.test.kernel.deployment.support.HAPartition">
  |     <property name="handler"><inject bean="HAPartitionCacheHandler"/></property>
  |   </bean>
  | 
  | </deployment>
  | 

(2) install

  | <deployment xmlns="urn:jboss:bean-deployer:2.0">
  | 
  |   <bean name="SuperDemand" class="org.jboss.test.kernel.deployment.support.SuperDemandCreator"/>
  | 
  |   <bean name="Manager" class="org.jboss.test.kernel.deployment.support.SomeCacheTreeManager">
  |     <property name="clusteredCache"><inject bean="HAPartitionCacheHandler" property="cache"/></property>
  |     <install bean="SuperDemand" method="createDependency" whenRequired="Instantiated">
  |       <parameter><inject fromContext="name"/></parameter>
  |       <parameter>Partition</parameter>
  |       <parameter>Configured</parameter>
  |       <parameter>Start</parameter>
  |     </install>
  |   </bean>
  | 
  |   <bean name="HAPartitionCacheHandler" class="org.jboss.test.kernel.deployment.support.HAPartitionCacheHandler"/>
  | 
  |   <bean name="Partition" class="org.jboss.test.kernel.deployment.support.HAPartition">
  |     <property name="handler"><inject bean="HAPartitionCacheHandler"/></property>
  |   </bean>
  | 
  | </deployment>
  |
