Make the Activity Log queryable, exportable and analyzable

I'd like to see the Activity Log information be able to be quereyed, analyzed, exported, etc for true multi-attribution modeling. I would like to be able to use the Activity Log to backtrack and see changes in lead behavior using analysis tools more comprehensive than RCE, along with enriching / overlaying with other data.  Open up the activity log for our queries instead of just a few objects. Make it so we can own our lead data, store it in our data warehouse and do trend analysis.
