I haven't found any other file systems that directly support HFS meta 
data...  however, you mentioned in your post trying the "mount a NAS 
based sparse file" approach but that it was unreliable.  Honestly, I'd 
fix whatever on your network is making this unreliable - I use this 
method extensively and haven't had any issues with it.  I currently back 
up over 100 MACs with various forms of NAS mounts, sparse files, ditto, 
asr, and rsync.  I might have a couple failures a year running nightly 
backups, and honestly even when I've unmounted a sparse file dirty, its 
never resulted in data loss...  if I were you I'd head back towards that 
strategy and make it work.
