It seems like things are picking up a bit in the arena of Open source EDI, BOTS is getting better http://bots.sourceforge.net/en/index.shtml
And I just ran across this implementation of AS2 written in VBscript! http://code.google.com/p/babelas2/ can you believe that! You do know that most businesses pay a lot of money for their AS2 software…. it is insane!
@Michael – Thanks for your feedback! My goal by using VBScript was to show that AS2 is not “rocket science” 😉
I have also implemented a NO SOFTWARE solution for “Managed AS2 Service”, you can have a look at http://www.as2box.net/ – there is also a 4-clicks demo described at http://babelabout.blogspot.com/2010/01/as2boxnet-yes-it-can-simpler.html
