Anyone write an EIS/OLAP system with drill-down using VFP?

We looked at Cognos Powerplay which was very good but decided our needs exceeded its limitations in number of rows, dimensions, etc.. So we are going to roll our own.

Hearing from anyone with advice who has done this or used some add-ins, etc.. would be apperciated.

Thank you,,
