I haven't abandoned this thread, just in case anyone was wandering. On the contrary, I am watching and listening with great interest.
There seems to be a fairly heavy weight of opinion here, and it's good to see it being exercised on a forum at last.
I am working solidly (within the limits of my limited spare time) on structuring some ideas about this, so please keep the information coming.
Regarding the stupid profile I have adopted - I am surprised anyone would have inferred anything from it, as you surely wouldn't expect me to use my real name would you??? <img src="smile.gif" border="0"> But, thanks for pointing out that the glass is really brown, when I just thought I was never finishing it....
