I'm researching what's needed for EDI as far as protocols and server/application setup. This is transportation industry and I'm interested in X12 format for transactions like 204, 210, 214.

What about AS2? Can it have server only on one side? Or both partners should be able to push?

I also was able to develop our own AS2 server and sender based on IIS WCF stack + EldoS EDIBlackBox
