Interesting. I'd be a needing to keep ACLs and other extended attributes 
as well though, which is something many of the UNIX-native archivers 
can't even handle. I don't see any indication that Info-Zip can either.

I'm not currently using ACLs very heavily, but I'm increasingly getting 
frustrated with the *NIX permissions model (just let me put a group in a 
group, dammit!) and expect my use of ACLs to increase. Especially once 
NetATalk gets decent ACL support.

ACLs can easily bloat into unmanagable messes, but well used I'm 
increasingly suspect they'll make life a LOT easier than the current 
set-up. It's not like our needs are even all that complex...
