I think the problem is that you have to interpret the user query (Solr has one syntax, other sources have a different one) and then combine results (how?). All of those are non-trivial.
Have you looked at something like http://www.comcepta.com/en/enterprise-metasearch.html which builds on top of Carrot, which integrates with Solr among other things. You can test their federated search at: http://www.etools.ch Regards, Alex.
