Within a couple weeks, this is going to need curated categorization of products. At the highest level, I&#x27;d categorize as:
a. physical product
b. installed software product
c. web service product
d. hybrid software+service product<p>Could be even broader. Or use tagging. You probably wouldn&#x27;t look in the above categories for performance events, dining out, or phone sex. Must decide how wide a net you wish to cast, and what ontological approaches to use. But this, in my opinion, is where it gets interesting.
