Bonnie,

Thanks for the sample, although it resembles my CarBoat class <g> and I completely agree with it; well, I've never disagreed with the advantages of simulating MI thru interfaces, but I also happen to believe that it can become also a very complex to maintain design, if you read my original post I kind of hinted this

I will not comment much on it other than saying that when you said "OK, so it doesn't follow your example hardly at all. Oh well" in reality you are not following the requirements asked to Doru and that was my criticism to it, that I could not see why the use of interfaces simulating MI were needed for it.
