I see that markablue was concerned about the consequences of starting this thread with a 

question 

Please don't be too concerned ... it was a good question ... one that needs a more technical answer than the usual answers (the 'we don't see it happing now', or 'we don't see anything wrong', ... kind of answers) that I've seen far too often elsewhere ...  

Please continue to ask questions ... they are one of the best ways to learn something.  After all, whenever someone asks a question, we can be reasonably sure that they want to get an answer ... and that our efforts to get and voice that answer won't be wasted.
