We have clients that use this add-in extensively to import data from ESRI .shp files and MapInfo .mif files. Basically, it overlays those data onto MapPoint maps. It also give you a properties viewer which is a floating window that displays text data associated with the shapes.

The company is Visimation. They specialize mostly in Visio but I understand they also do MapPoint custom work and this tool came from that. The GIS Data Import for Microsoft MapPoint product page is here with screen caps and feature descriptions:
