Our team at Applied Information Sciences (my employer for the past 11 years), just completed the certification process for the add-ins they wrote for MOSS 2007. AIS had a signficant amount of development to do to make MOSS compliant. The faith Microsoft put in us, to develop for a core product an add-on which Microsoft will make available under their own name, is significant and (in my opinion) well-deserved. The team did a great job making all the customizations and getting through the certification. An added benefit is the real in-depth knowledge we gained on the inner workings of MOSS. We'll definitely leverage that on other MOSS projects going forward.

Congrats to Russ, Steve, Alex and the rest of the team! You can read more about it through the press release and Microsoft ECM Blog
