Steve's Comments from the link above:

IStringResourceLoader is the interface:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/resource/loader/IStringResourceLoader.html

Theres some info here about connecting it to a Spring message provider:
http://www.jroller.com/eyallupu/entry/spring_as_a_message_provider

There is a very basic custom one in Profile2 already:
https://source.sakaiproject.org/svn//profile2/trunk/tool/src/java/org/sakaiproject/profile2/tool/ProfileApplication.java

which just loads the resources from a different location. So it should be easy enough to extend this to use the Spring based on in the kernel?
