Barry, I understand your need and I agree with you it'd be useful to be able to load AEs also from filesystem, I created SOLR-2501 [1] to track that requirement. Consider that loading AEs from relative paths, as using relative paths in general, is not a good practice since different environments could set the relative path "start" at different points in the filesystem; I think a good solution would be using the solr.home as the root of a relative path because that is a Solr instance/core property.
