Re: OmniGraffle Support

On point 3, I specifically had issues with Graffle files stored as bundles on a networked netapp share mounted through NFS to an OSX desktop client. From time to time, OG would lock up, be unable to save files, and crash. I also found that performance of OG was also affected and significant slow-downs would happen with some operations. I found that switching to using flat files prevented these problems, but recent versions of the application combined with updates to OSX's networking code may have also dealt with these issues.

Note: base64 only adds 33% to content size. Also, any file can be saved in
Subversion, but storage efficiency may be improved using a text based
format, as well as the ability to diff versions of the file with meaningful
results. But even the use of text formats, e.g. XML, do not necessarily
guarantee that you will be able to reasonably deal with diff info. The
degree to which you can depends largely on how an application uses XML.

On point 2: as long as Sharepoint allows binary files to be stored, and if
users only modify and publish versions one at a time, with locking imposed
(supported) by Sharepoint, it should not be necessary to use the flat
format.

On point 3: any file can be shared over a network disk, if what you mean is
just making directory structures available across a network using NFS, Samba
(NetBIOS), etc..
