I didn't mean to sound as though I'm not taking it seriously. That was the entire reason for stating twice in no uncertain terms that I've done no research whatsoever -- to illustrate clearly that I'm in a position that very easily could be wrong. As it seems, that's the case after all. If I didn't take it seriously, I wouldn't have bothered answering you. As it was, I found it interesting enough at the moment to contemplate and write a sentence or two about.Later I'll find it interesting enough to read a white paper on. Just not right now... :)
