But I am still scratching my head to why we would need 2 implementations of BD?
I used the Front controller for the web tier. It communicated with a web based implementation of the business delegate and my swing client communicated with a standalone client based implementation of the business delegate. Both the clients used different implementation of business delegate. The swing client communicated directly with the ejb tier (via the swing business delegate). I had only 1 business delegate (it didnt end up looking very gigantic as the methods were pretty coarse grained) per client, but several session facades.
