Right - thats the key point. Theres an incompatibility between the
design of idle-suspend and between the use of salut collaboration (or
with the use of any multicast-using application).
And even if we did wake up on multicast, we frequently fail to wake up
on network even when we're supposed to
Increasing the frequency of "I'm here" communications would help this
issue but you'd end up saturating the network even more that already
happens, and I predict that it still wouldn't be reliable.
Best short term solution would be to disable idle-suspend, or at least
disable it when salut is being used.
