Nice clear overview and some good points. I know you'd like the article to be generic, but out of interest, which appliance was implemented in this particular case?

I implemented an appliance in a Telco back in 2003 and came across all of your points. 5) was interesting as it taught me that SPs are simply not required in MPP systems... pretty much every procedural operation can be done by breaking the logic into chunks of standard sql and applying them incrementally, but incredibly quickly due to the performance of the system - so SPs are a hang-over from traditional OLTP systems just like indexes in my view.
