Hi Dan,
I developed this initial interface with iPardigms, the interface is written to comply with the functionality they have requested. I am currently discussing with them the possibility of developing a deep integration API to their system so I would definately like to see what you have done so far, at the moment the discussions are in the early stages and are only discussing the possibility of deep integration mechanisms so this is great, it might be a means to kick start the dialogue further on the deep integration and provide the workflow thats needed.
