[OpenAFS] Cross Platform Forks et al

[Jason C. Wells]

I have become fond of windows desktop search.  One of the things that 
makes WDS useful is the metadata that can be stored in what NTFS calls 
alternate data streams.  Other file systems have an idea of alternate 
data streams in extended attributes (UFS,ZFS) forks (HFS).

Is it useful to consider one's approach to metadata when selecting a 
filesystem?  Is cross platform compatibility even possible?  I see that 
streams are on the wishlist for AFS3. 

Later,
