Paul,
The only real way is to have a module that intercepts the i-bus signal. Here's an outfit in Europe that has these for 99 Euro, but if you do any research you will find that the vast majority of people that buy from them regret it because of lengthy delays in shippping and sometimes even no product being delivered at all -

As for compatibility issues, no there shouldn't be any issue with that at all.
