Re: Radical new idea
IrDA and the like has indeed been around forever.
And site-to-site infrared / microwave systems too.
They have serious problems that stop them being used for anything other than consumer toys (IrDA way surpassed by Bluetooth, line-of-sight kills anything but use over your own land or free space).
Been trying to convince my employers to put in site-to-site-links but the only places that can "see" are in positions that would show the ugly, and they disapprove.
Instead, we spend £10k a year on a Virgin leased line and another £10k on a BT leased line at the other end (because no one supplier covers both areas... sigh). When I can see each building from the other. Just a shame we don't own all the land in-between because I'd just get them to chop down a couple of trees and problem solved.
