The procedure for using a custom key mapper:
1. Add the following property to the <jdbc-store/>:
 <property name="key2StringMapper">class.name.of.key.mapper</property>
2. Add the jar file containing the above class and its dependencies to:
$JBOSS_HOME/modules/org/infinispan/main/.
3. Edit $JBOSS_HOME/modules/org/infinispan/main/modules.xml and add a reference to the jar within <resources/>.

I'll make sure this gets added to the docs.

Yep, those attributes are optional, whereas servers is required.

There are only 4, right?
We can certainly instruct users on the procedure to add the relevant cloud provider jar to the jclouds module.
