We'll add this to our next dev build.
In our next build, we will be doing two things [1]: 1. enabling the patch 2. disabling wake-on-LAN It seems to me that this is the preferred solution. I think we only need to inhibit power management when collaboration is active, not for any LAN traffic. Living up to its name, wake-on-LAN keeps the XOs awake whenever a network connection is active, even when you don't really need it to be. Assuming that it always works as intended (which as you have explained, it does not), the patch won't be very testable when it is active. erikos reckons that the patch won't do much [2], but the testing performed so far seems to be small-scale. Hopefully we'll get some feedback on this after we put out our build.
