Payment Gateways other than stripe

First of all, I must appreciate the product as it's been a long time since I've seen such a well thought and realistic form builder. 

Since people are purchasing it from different part of world, ability to use custom payment gateways would be so majestic with all the existing features. 

My personal hurdle (only I guess) with this was getting paid through this form in OMR (Oman's currency). Stripe would work, but it doesn't have this currency and there is no way I can integrate local payment gateways in deftform.
