sorry, yes you’re right regarding the process. it is alot of core changes you need to make to include this as you would need to edit the init.gz to include rsync and would also need to include the location patch to determine which storage node to pull it from:

however this is coded based on 0.31 and it’s not being included in the future releases but may be able to use the new core and hook functionality to include this but this is all on hold really until 0.33 is ready for production.
So to summarize you would need to make alot of changes to use it in this way - maybe someone else has simpler solution to suggest?
