Greg,
It's funny to read your plans as I am actually in the process of preparing a session entitles "Managing your FlexCast environment with System Center" for our Synergy event next week in Berlin. Good see Jo on here as well and give you some pointers. I can tell you this board has given me a lot of help while preparing and I'll be making a big HOWTO guide based on a lot of info I found here and things I found while preparing for the Citrix community. You also looking into the SCCM connector for XenApp within your project as well? This would make application deployment from 1 central hub into a blessing however it was designed for SCCM 2007 and I have not (yet) tested it with SCCM vNext which your post hints at.
Good luck
