thanks for all the replies... it does makes 'sense'
.
am still at the approval stage but wanted to 'wire up' the house.. but not all the bedrooms (well for now..)
was thinking a wired lan to the study, home theater room and one in the family and all the while, my sensible place is the study where I have a few external hdds too. so maybe a cupboard or something
but that may change, because of what I have read.
