Integrating IR or RF remotes

I would like to integrate my current control system (for home entertainment, screen control, shades control, light control etc) into the Vera. Today I use a PC and the program GIRDER together with a USB based IR receiver and a Logitech Harmony RF/IR remote. I would like to be independent of the PC. I am currently expanding my home automation system with the Vera system and my quiestions is specificaly: How can I integrate a RF/IR remote to the Vera. The controled devices will be Zwave devices. I am able to do some programing and I know the LUA scripting as that is also part of GIRDER. Rgrds Ole
