Wow- sounds fascinating- I am not at that level of tech geekiness but I do remember asking about the platforms used, stability, scalability, storage capacity etc- it seems you are breaking new ground here! I'll get a hold of THECHAD- he is one of my contacts.
A good person to talk to would be THECHAD...he's around here somewhere. I'm in charge of getting data to and from the states and the DEA. So it's like XML hell ova' heyah. But I'm really taking .net to all new levels, writing webservices, integrating with autocoders, interfacing with a websphere translation server, etc, etc... Two words for all of this woud be "something awful".
