>One of the big advantages I see of SP's vs. RV's, that I haven't seen mentioned yet, is that RV's are a VFP only mechanism. If you need to access the data from other non-VFP applications you're going to need the SP's for the other applications anyway.

Like I have stated in other messages, this is less an argument against RVs than it is against putting data access logic in the front end. If you have a middle/data access tier, this isn't an issue.
