One reason I have mentioned android devices is because I know they have a
free EQ app on them which will allow us to tune the output from the phones
to the enclosures of the speakers which allows for optimal volume of sound,
I know they have a team speak app, I know that people upgrade them with
frequency so we should be able to source free devices, and I know they can
be rooted with our own choice of ROM, all of which may not be necessary or
desirable.  I am willing to go with whatever solution we can muster.
