Jeff, you can get a DW request in tableau format and be done with it (of course doable only if you have tableau which is worth it). For the data feeds, they can be humoungous but unless you really need to dig at the hit level data and are looking at building a DB or find a discrepancy, it's a waste ...

Absolutely, this is a great idea and should be a no brainer since Adobe is pushing context varibales also in the mobile SDKs. There is a definite need t be able to test the rules we set.
