We do plan to add this as another free payment extension for karzina but we were waiting for the bug storm to die down first. All of the opencart code gets reviewed and tested before we include it. I know that I will have to change some of it.
I will bring this process forward for you but could not hope to deliver anything before this weekend. Would you be willing to help with the final testing?
The other thing I should point out is that this particular payment extension (SIM) is similar in function to the standard paypal one. It redirects your customer to authorize.net to make the payment and returns them to your store afterwards.
