Hello, I am interested to contribute, few suggestions. I have been programming ATM/EFT Switch for long. 1- Let us make it generic transaction processing switch not IFX only as in real world IFX is not in so much use(NDC, Agilix dominates ATM/CDMs) 2- There was a similar project long time back on sourceforge, Open EFT Switch. It has been removed, don't know why. I have its architecture documents, I downloaded. May be we can start with that. Thanks, Maverick.
