You know, I think the real answer to that question needs to be based on 
whether we think that ABE is an all-around useful feature, or just 
something we need for feature parity with other Windows file servers.

If it's an all-around useful feature, then we should put it into the file 
system (to support local users) and maybe also put it into the sharing servers.

If it's just for feature parity, then by all means confine it to CIFS.
