any specific

I *think* the missing step here is that while DocLists can't easily be
modified, new SolrDocument and SolrDocumentList classes have been
added since 1.2. Solr by defualt doesn't use them, but the built in
Solr
ResponseWriters can output them, so your custom component can build a
SolrDocumentList bsed on the DocList, and add whatever fields you
want.
I'm not sure if there are any help methods to do the
DocList->SolrDocumentList conversion.
(Ryan: keep my honest if this isn't what you had in mind)
Correct -- there isn't really a clean way to do this.
For an example, you can check the "locallucene" query component:
https://locallucene.svn.sourceforge.net/svnroot/locallucene/trunk/localsolr/src/com/pjaol/search/solr/component/LocalSolrQueryComponent.java
(towards the bottom of process)
that adds a calculated "geo_distance" field to each returned document.
