did a quick search and did not see this anywhere, found it today on engadget.com
Motorcycle Air Conditioning by EntroSys (http://www.youtube.com/watch?v=LnEibndWyQU&feature=player_embedded#normal)
pretty cool idea, basically takes your pillion seat to mount, but, provides heating and cooling. not sure how i feel about the giant tube connecting to you though...
on second thought, maybe it doesn't connect on the pillion, not sure how it would adapt to the monster though..
I could see a unit like that being useful if I lived somewhere really hot but beyond that... Kind of a PITA.
I can certainly see some great benefits since we live out in Arizona and riding in 120 degree heat for any period of time is awful...
