using SFS for server-side home dirs

Hello, I'm looking into using SFS.  
Of what I've see so far I like SFS a lot.

I'm looking to replace NFS on one of my network and am looking to use SFS but 
I'm running into a slight problem with permissions.

note: $USER is NOT literal.

I get: sfsrwsd: readdir: /home/$USER: Permission denied

My current setup on the server the home dirs are 0700. 
I would be willing to change to 0750 as $USER:sfs, so that sfs can 
read /home/$USER. 

I'm not comfortable setting /home/$USER to 0755 which is what I believe I have 
to do now, (at least that's how it appears) to be able to use SFS for sharing 
home dirs.

Currently I have the home dirs being exported to clients in the domain and 
they show up on client machines as:
/home/$USER/home-on-server/


So in the long and short of it does SFS have any access control lists built in 
for resticting users and/or does it support native FS ACL's?

Thank you for your time,
