(I'm new to the list.  I looked around and could find any information on this topic.)

Has multiple for support been considered for rsync?  I would personally find it very 
useful.

At least two major files systems that I can think of support forks: HFS and NTFS.

I'm mostly interested in fork support under HFS mounts.  With the deployment of Darwin 
and OS X there would be many uses if rsync could move more parts of a file when 
syncing.

The HFS+ file system supports any number of forks in addition to file meta-data.  
Under Darwin and OSX, there are two forks used: data (the primary) and resource (named 
rsrc).  It also uses Finder info stored in the meta-data, that includes things like 
the creator and type codes as well as several flags.

Apple has already standardized the way to 'split' named forks into adjacent dot files. 
 Thus allowing multi-fork files to be moved to single fork file systems like UFS.  In 
the same way, rsync could drop forks onto multiple files when destination file systems 
don't support forks.

I probably couldn't completely code the solution, but I might be able help.  If 
nothing else, I could come up with some thorough tests.
