I think it would be useful to have arbitrary chunk sizes in Syncany. In all cases where there is an insertion to the beginning of a file that is not of length 512, the rest of the file will be offset and all subsequent chunks will be marked dirty and discarded. I think it would be useful to have a procedure that tries to find existing chunks in the new file and generates a minimal changeset. This might result in fragmentation as smaller and smaller chunks are created, so there should also be a feature to combine fragments into larger chunks so that filesystem performance isn't degraded.
Anyone have any thoughts on this? Should I file a blueprint for this? See Chapter 3 of Andrew Tridgell's thesis for more details about how rsync accomplishes this: http://samba.org/~tridge/phd_thesis.pdf
