Here's what I think. I am trying to encourage everyone - and yes, that 
includes myself - to think out of the box. It's very easy to say 
something cannot be done, or can only be done some cumbersome way. But 
usually, those answers come from straight within the box. And they come 
with the entire garnishment of irony, sarcasm, "proofs", what have you. 
But once we stop glorifying the box and decide to get out of it, 
solutions will be found - and they might even be better. :o)
