Easy enough to check this out with a router and a smartphone to make sureD
that there's no deadspots because of the walls. If there aren't any, this
would work well and would avoid the problem of user interference with
playback that a player-based system can have. Wi-Fi could also be used to
send regular clock signals out to a player app on the smartphones to
ameliorate such user interference since the app on resuming could continue
from the right place in the soundfile. With this approach deadspots would
be much less of a problem.
