Appointments+, Paypal & Other Bank

Hey,

I appreciate that you can link appointments+ to paypal, accept payment and confirm appointment. However, I am accepting payments on my website (once I am PCI Certified and I have an SSL certificate etc) with using a company called Moneris. Can I still integrate all this with Appointments+ or do I have to use Paypal? If I can use my proposed setup, is there anything I should know from your side?
