There was a bunch of stuff on a site called www.cdaexchange.com but that doesn't seem to be available any more.

You check out some of the work that Roddy Rodstien (formerly at at Citrix, I think he has moved on now) did with his 'in a box solutions' check out some of his stuff over at http://rnetworkx.com/index.php?option=com_content&task=view&id=18&Itemid=43

That should point you in the right direction, then if you have any specific issues, post back here and someone will try and answer them for you.

Hope this helps,
