Taxonomy as Organic Groups

Thanks to the incredible Drupal contrib module community, you can build a pretty complex site around tagged content (with the core taxonomy module) and Organic Groups (along with many other related OG contrib modules). We will discuss a recent, large, federal contract, where we attempted to build the site around taxonomy as organic groups. We will focus on where the contrib community saved us time/effort and where it cost us and what our eventual solution was.
