Perhaps nodes running on Android should have some sort of 'portable' flag 
they send to identify themselves, until the rest of the work is done in 
optimizing for portable nodes.

Since the node's own idea of its 'predicted availability' might have a 
wide variety of estimations, represented by numbers that may be real 
rather than discrete, perhaps these is a simple method to handle based 
upon algorithm. I'll have to give this some more thought.

The idea of power supply for transmission is an important one. Even nodes 
which are fixed may be battery powered, and when their batteries are low 
other routes should have preference. But such nodes would have a fixed 
location; so there should be a different attribute to indicate 
power-limited versus fixed/mobile location. A mobile node located in a car 
is one which has an unlimited power supply but is not in a fixed location, 
where as when it is parked, its power supply becomes limited and its 
location becomes fixed. A cellphone becomes stationary and of uniited 
power when it is plugged into its charger.

What I have said above is not an argument or thesis but just my thinking 
aloud, so to speak, thinking while typing.

I have much of the equipment needed to set up a testbed here in Boston, 
but so few people interested in mesh wifi enough to give their time. What 
a shame.
