Hmmm not sure if you could do both or even why you would want to do both. I have only used IRSC before and kinda wrote off BDS a long time ago as an open source system that may be good, but I saw no benefits over IRSC when I looked at. However I am not an M.E. so maybe someone can shed some light on the subject, but I can't see the benefit of it over IRSC which is pretty much the standard.
