Actually a simple solution I've found is unloading the core, and recreating the core passing parameters to the action=CREATE api call.

I think it would probably be a very major effort to change this, but there may be a much easier way that the project could allow properties that can change on reload. >From what I can read in the code, not even the filename in the "properties" >element in the core.properties file is re-checked on core reload.

Unless there's another properties file that I'm not aware of that *does* get checked when a core gets re-loaded, I think you've got an excellent use case for an "Improvement" issue in Jira. Here's the change that I think Solr needs: When a core is reloaded, all property definitions that originated in the file referenced by the "properties" property should be dropped and re-read.
