: The most important issue is to nail down the external HTTP interface. I'm not sure if i agree with that statement .. i would think that figuring out the "model" or how updates should be handled in a generic way, what all of the "Plugin" types are, and what their APIs should be is the most important issue -- once we have those issues settled we could allways write a new "SolrServlet2" that made the URL structure work anyway we want.
