Network 'CAT5' Cable

[breezer]

And those little walkie talkies claim theoretical ranges of several km, don't they?

they do, but they are very usefull, especially if you go to a big theme park. When i went to Disney in America, i got some more, very usefull, see most people with them

fibre is insanely expensive right now and with the coming of 1000baseTX is unlikely to be seen at the desktop for quite some time

if you want upgradability then the best option is probablly conduit with pull strings and GENTLE bends then you can put whatever cable type is the stadard of the day in
