This is a mod originally requested by Darkosto over on twitch while he was developing Sky Factory 4. I made a fair bit of progress but unfortunately due to uni and looking for a job I was never able to complete this mod. I am returning to this once other mods have had the attention they need.
The mod allows you to connect to the cloud and store items and blocks there at the cost of power and / or currency. The currency has a few options. This was set up so you could either have a custom currency(go see simple wallet) or use existing items/blocks to pay for the service.
Faster connections are more expensive and have more complex requirements. All cloud based storage needs some kind of portal to hook into to get a signal to the cloud.
