So more effort than it is worth?
Just get them to use modems or get their own adsl at home?
Either that or I could suggest they string their own cat 5 across the
street? Or blow up a few buildings in between?
Just =once= in my life - I would like a solution to be simple. To have a
cool idea and just be able to do it without some little problem or
artificial red tape getting in the way! :-\
:(
:)
