To echo your update on the original question: while AeroFS is a distributed filesystem with quite complicated mechanisms underneath, we work very hard to make AeroFS dead simple to use. Following this philosophy, we've implemented the features that you mentioned but they're currently disabled/hidden for the sake of simplicity.

Regarding offline computers: if the only computers that host a file are offline, the file data will be unavailable. Currently, offline files are invisible in Finder/Explorer/etc. Because the current system only supports full replication, having offline files should be a rare case.

Regarding performance: it's crucial to us. Lots of efforts has been made (and even more to be made) to ensure the filesystem has comparable performance to local storage; sync performance is another area that we invest a lot of time in.

Only full replication. So not a good idea for small devices.
