I had a great time at Houston TechFest this weekend.  I met a lot of new people and I got to see a lot of old friends.  At TechFest, I spoke about how to code advanced SharePoint BCS solutions using BCS entity models and custom connectors.  The slide deck is posted on slide share.  I’ve also attached the code for the custom connector I used at the bottom of this post.  If you have any additional questions, feel free to ask.
