While there are some smitherings about 10GigE, there are technical reasons and
market reasons it is not really ready for prime yet, that is not to say it's not going
to happen, it is just not going happen now.

I need a contact with the RCMP in Calgary (Alberta) concerning a network

If anybody has one, please relay off list.

I'd be interested to see if these actually save any money. I'd
guess that the cost of moving the air around is going to be a factor.

I've seen some designs that actually use water as the transport and
many-finned radiators at each end. Radiator transfer heat into cold water
inside which is pumped up a radiator in the sub-zero temps on the roof and
exchanged and then looped back.
Same basic principle as a traditional
There are indoor units that have multiple coil sets.
One can be utilized for mechanical cooling, the other
can be used for free cooling mechanisms.
For example, a water loop can be implemented
that rejects its heat via a roof-top evaporative tower.

Exactly. At the
I used to have a boiler heating system in my home (wood heat) that used
anti-freeze treated water tpumped from the boiler in the garage through
the house and back. Water is great for moving heat, but you do need to
treat it so it doesn't freeze and burst the pipes.

The backbone at the time of my original work that I participated in was 40Gits/in and 40Gbits/out unless that has changed 10GigE is not practical or cost effective if it is limited to local area's and provate connections. That doesn't mean from A design
perspective thatA cost effective solution

Deploying anything 4x faster than what you need is not cost-effective, ever.
Even deploying GE where 2xFE would work is more expensive.
