I'm a bit late on this (been vegging out with the kids since I got back home) but attached this to blog entry are the files and slides I used at my BACFUG presentation last week. You can view the recording here: http://experts.acrobat.com/p24637610/
I want to thank the BACFUG for having me, and thank Donald Booth (one of the Spry engineers) for helping me out during the presentation.
