Dual ports - infer or megawizard advantages/disadvantages

Yes I have read the coding guidelines thanks. I think the portability issue is very relevant, more so for us now than a few years ago as it happens. My own opinion is that yes, inference would be better in this regard or at the very least have some form of portability layer to shield the important bits of IP from reliance on specific hardware if at all possible - that's kind of the approach I have taken until very recently.
