Hmm.  We have had this discussion before, about ethernet cable between 
buildings.  In general it's probably okay- that is to say, a link from your 
house to your garage or sleepout, but... you can get into trouble with long 
runs, and connections to houses on different mains phases.  For 
'professional' installations it is not recommended unless you have spike 
suppressors and lightning protection etc.

Secondly, when my previous company wished to install a wireless link across 
the city they had to apply for a resource consent.  At the time this seemed 
absurd to me as the wi-fi equipment is designed to operate in the 
license-free band and is considered to be safe.  Not only that, but there 
must be hundreds of home wi-fi hotspots that are 'visible' on the street, 
but do not have a resource consent.  However, it had to be done.  You 
should check to see if this is still a requirement.

Finally, on the subject of wi-fi, you will find that your link will never 
reach 54Mbps, generally because of all those hundreds of other home 
hotspots pointing back at you from the city.  It only takes a couple to be 
pointed in your general direction to start collisions and contention which 
will slow your link way down.  For example, one of the Yobbo links is 
pointed out towards Linwood (and on to New Brighton).  I suppose if you 
have a tight beam then you might be able to reduce the overlap with other 
signals.  Another option is a laser link...

Good luck!
