Filetable Maintenance:
*v1: vdrive-based tree of MutableDirectoryNodes, persisted to vdrive's disk
no accounts
- v2: move tree to client side, serialize to a file, upload,
- vdrive.set_filetable_uri (still no accounts, just one global tree)
- v3: break world up into accounts, separate mutable spaces. Maybe
- implement SSKs
- v4: filetree
+ v2: filetree, one space per user, plus one global mutable space
+ v3: maintain file manifest
+ v4: figure out accounts, users. Maybe implement SSKs
Checker/Repairer:
*v1: none
+ v1.5: maintain file manifest
v2: centralized checker, repair agent
v3: nodes also check their own files
