Hello Mark,

no, there is no intention to change one of the main design decisions,
whole file caching. More or less, it is whole file caching that
makes Coda semantics possible.
There are other filesystems which do not target disconnected operation and
read-write replication. They can do without caching or with partial

In contrast, it would be possible for Coda - with some effort - to make
open() return before the whole file is fetched. No certain plans though,
to the best of my knowledge.
