Thanks in advance! > Hi Gulyás, At a very high level, this sounds plausible. It is true that different organizations can collaborate to form a Tahoe-LAFS storage "grid". We talk about the "grid" a lot but you really have to apply a lot of abstractions to create this *concept* with Tahoe-LAFS right now (though there's some work underway to turn it into a more concrete thing). A Tahoe-LAFS "grid" is just one or more storage servers being used together and you have a lot of flexibility around where those storage servers come from. It's true that each volunteer/service organization could operate one or more storage servers and that a Tahoe-LAFS storage client could be configured to use any and all of these servers for storage. One area that you probably want to think about more is how those organizations coordinate with each other in their use of these servers and the creation and consumption of content on them. For example, would it make more sense to have a fully open grid or a private grid open only to participating organizations? A fully open grid can accept contributions of resources from more participants but it also gives out storage access to more participants as well. A private grid might make more sense but comes with operational security requirements to ensure it remains private. At the content level, how would different organizations offer content to save other organizations labor? Perhaps each organization maintains a directory (or directory hierarchy) which only it can write to but which all other organizations can read from. This might be done on an ad hoc basis or with a tool like magic-folder <https://github.com/leastauthority/magic-folder> (which is currently very much a work in progress). Then organizations would browse the read-only directories shared with them by other organizations to see if the desired content already exists. If found, they can retrieve and use it. If not, they can create and upload it. This seems workable - however, I wonder if there is an advantage to using Tahoe-LAFS over another system. For example, Google Drive and Dropbox would offer comparable experiences, I think, without the need to operate storage servers. Or, to avoid proprietary, centralized systems, NextCloud has file storage and sharing capabilities. It is not a distributed system but it's easy to find a commercial offering that could be shared across organizations. This comes at a cost - but so does operating Tahoe-LAFS storage servers, and I suspect NextCloud hosting is price competitive (unless volunteer labor can be discounted, perhaps). Or maybe it is the case that the loose group of organizations actually benefit significantly from the distributed nature of Tahoe-LAFS - perhaps because the operation of the software more closely matches the relationships of the organizations to each other? Does this make sense? Does it help? I'm happy to consider any follow-up questions.
