It sounds like the correspondent (Jonty) is thinking just in terms of SolrJ -- wanting to share that across multiple threads in an application server.
In which case the question would be whether it would be possible/safe/efficient to share a single instantiation of the SolrJ class(es) across multiple threads. Of that I have insufficient knowledge, having not worked with SolrJ. However, if instead the correspondent were to just connect directly to Solr via HTTP to a single, shared, Solr instance (without SolrJ) and manage the XML himself/herself, then there would not be a problem at all.

This would be outside SOLR per se. A few caveats though, I am not sure if tomcat supports keep-alive, and I am not sure how SOLR deals with multiple requests coming down the pipe, and you will need to deal with concurrency, and I am not sure what you are looking to gain from this, opening an http connection is pretty cheap.
