Ah, yeah, true. Not sure why that slipped my mind. Probably had Solr on the brain.

I'd rather integrate Spring. But you've heard me on this subject on Solr before.

We are starting to get a couple of places where users can insert their own custom implementations. Recommenders, Weight calculators (new today) and some other areas are all prime examples. Currently, it is likely the case that one has to do the whole un-jar/un-war dance in order to add their stuff
in.

Solr had this problem and solved it through a custom class loader and the Solr Home capability. Essentially, Solr defines a HOME which has a lib dir in it. When someone wants to put their own custom code into Solr they merely have to jar up their code and drop it in the lib directory and then
tell Solr about it.

Any thoughts on grabbing this functionality (SolrResourceLoader) and
modifying it for Mahout for some of these things? Not sure how it would play out for things running in Hadoop, but for both Taste and the utility
functions it seems like a win.
