Hal,

The background on the mounting and availability of the EOS is one of 
survival.  It is designed to provide the required 10 minute supply of oxygen 
in case of cabin de-pressurization, so you don't have to do an "emergency 
decent" if the conditions are not conducive to safety.   So:
1.  Mount the bottle in the side wall by your left leg so it can be turned on 
without changing your seat position.  Under the seat doesn't do the job. But 
if trhere just isn't room due to all that "other" stuff,  Mountain High has 
remote controls available for panel mount or whatever.

2.  Possibly the best place for the outlets would be in the side consoule 
forward of the stick, where they are out of the way, easily acessable yet not 
pointed up like a trash collector.  One builder had a little recessed pocket 
built into the side panel that held the mask and outlet and covered with a 
simple cloth flap.

3.  The masks should, at a minimum, should be plugged in any time you are 
planning to operate above FL180.  In this case all you have to do in case of 
de-pressurization is to turn on the valve (1/4-1/2 turn) and slip the mask on 
while you are declaring an emergency and telling ATC that you have to decend 
immediately.  

Time of Useful Consciousness (TUC) is the period of time from the 
interruption of the oxygen supply or exposure to an oxygen poor environment, 
to the time when useful function is lost.  You are no longer capable of 
taking proper corrective and protective action, but are still conscious.  It 
is not the time to total unconsciousness.  At higher altitudes, the TUC 
becomes very short.  Exercise or stress will redcuce these times.  
Additionally a rapid decompression can reduce TUC by as much as 50%.  Mean 
TUC for resting individuals are:  
FL180   20 to 30 minutes    
FL250   3 to 5 Minutes
FL300   1.5 to 2 Minutes
