    Thanks Ed. Using Collab tools is a great suggestion. I also received a suggestion of using a wiki such as PB wiki rather than the handouts. I think the Wiki suggestion is along the lines of what you are suggesting.

    Hi Joe,

    This approach sounds very workable. My first thought would be to see about using collab tools like Google Wave and Acrobat.com to support the development. Corp America is starting to get eLearning but too often they dumb it down.

    Cheers!
