I'd stay away from Gluster for home directories... too many small 
files.  The performance drops dramatically.  I used gluster for virtual 
machines images, and performance was good.

My solution for syncing home directories turned into using Bittorrent 
Sync.  Replication isn't immediate, but it's fast enough.  I also 
decided to sync only a single directory and not the whole home dir.  
That way, as a user, I could specify what I wanted to sync and what I 
didn't.  For example, one machine has a huge downloads directory.  No 
use syncing that to my Mac laptop.
