What I find missing from all the OSS analytics is log parsing agents that I can install on my servers for sites that I don't want to have JS on. The agent would parse the logs periodically (every hour from cron or whatever) and send the parsed/analyzed data to the server handling analytics. This could also augment data for sites that primarily use a JS tracker by adding information on users that have JS disabled (or users on such a bad connection that they leave before the load finishes) as well as bots, uptime checkers etc.
