If it's ok having everything in a single file per directory,
then just create a new magic number and define your format.
Keeping the format similar and simply appending variable-length
data per-file would be good.

I should have added a flag for optional per-file data.  But a
new magic number is an easy change.

Beyond the file format, I assume you are planning on transferring
all the POSIX and ACL data together with the normal attributes.
I assume this data doesn't get too big, so there is no need to
also use an rsync-like algorithm on this data...

How about apple resource file forks?  They should probably be mapped
to a separate file (like xtar), rather than considered part of the
attribs.
