This is a long (2 hours, 17 minutes) video of the full Zulu and DocuBin presentation that John Sindelar and Jesse Barnum did at the Philadelphia FileMaker Pro User Group. There were a lot of really good questions and we went into a lot of depth on demos, so if you’re considering either of these products this is a great way to learn a lot.
