Uhhh. It's been a long time since I worked on such a system (1975 I
think),
but IIR the prop delay through space for moderate distances kills the
idea.

That was 1975. The only people who ever were exposed to any propigation delay
where those rich enough to make a long distance call that was routed over
satellite. If I remember correctly it was about $5 a minute to call New York
from L.A.

This is 2011, everyone is used the the propigation delay of digital telephones,
and VoIP. 150ms is tollerable.
