Dear Brian and Patrik, great contributions to the dialogue on this.

Just to remind you that many in this list do not dominate the myriad of 
acronyms and associated concepts on this track, so it would be great 
(and educative for many of us) if you tried to explain DSLAMs and LLUBs 
and son on, when such mentions are needed, to most of us poor mortals, 
Wikipedia and Google notwithstanding :)

fraternal regards
