So far looks good, I am testing it tomorrow,
you doing quick work! :D

GridFlags.COMPRESSED_CHANNEL might not be necessary. Except you want to prevent them from being tunneled through another network. But besides ME no other tunnel has this limitation.

GridFlags.COMPRESSED_CHANNEL

Ah, right. I oriented myself on the ME tunnel for the IGridTickable implementation and copied that over for testing, forgot to remove it again. Removed it.

Also, if you test with OC the way I did (computer on one end, screen on the other), in particular that it keeps working after exiting and re-entering the world, make sure to use the latest OC dev build's OpenOS. Depending on the time it takes for things to initialize on chunk load, there was a scenario where GPUs could forget about their screens, but the screens could be back before the computer resumed for the first time, leading to the OS assuming the GPU was still aware of its screen, where it really wasn't. Fixed that in OpenOS now. So this implementation turned out to be a really good test case for that behavior!

Tested it, working fine for me,
send you a PR which you can merge,
this includes some style fixes and other random crap, the commit message should help

Merged, thanks for the cleanup!

just rebase -i them out. I think thats just nicer and faster than somebody bossing around to fix this and that

Sure thing, done!

Thank you for your contribution!
