Beekeepers managing AHB and interested in controlling
response from human breath may be interested in an
'Avalung'.

The Avalung is a vest with a breathing device that
redirects breath and disperses it behing the person
wearing it. This was developed by Black Diamond to
allow people to breathe while trapped under compressed
snow in an avalanche.

A description can be found at:

http://www.avalanche.org/~lsafc/TUTORIAL/EQUIP.HTM

Buy it at:
http://www.bdel.com/gear/avalung_ii.php
about $120

I intend to try one during my next AHB session, but
would be interested in any comments/reviews from other
users.
