I've created a new version of the onlinescreensaver extension which works on the PW2. The original version had a problem, because the PW2 does a different hibernation technique, which stops the kernel from waking up after going to sleep.
For non PW2 users, this version should not have any benefits.
Im happy if someone wants to give it a try (and some feedback)
