>Does that help?

Yes, it does... I'm still unsure about taking this piece of the contract on though. How is all this different from (something very simple like) creating a flat file in an app, transfering the file to the destination server and having an app on the receiving end read the file? Is that EDI, but without all the bells and whistles (and intermediaries)? If so, then I've been doing a form of EDI for 12 years. That's alittle tongue-in-cheek, but it sounds like the EDI software/standards are just checks and balances to make sure that everything is in sync... Is that somewhat true?
