> I think this maybe way off topic so if anyone knows of a good > discussion forum for this topic please advise. It's in OT so it seems very fine to me. Other opinions may vary :-). But I saw at least one admin commenting so I'm not alone. It seems that this sort of thing is used by and of interest to a significant % of more technically capable list members. If the list can be useful to exchange ideas of mutual technical interest and it doesn't noise up any topic specific areas then I see no problem.
