[Samba] About NAS versus Samba

I use a Netgear readynas1500 as a fileserver for my Samba3/ldap domain 
which I' ve just upgraded to AD and it works fine in both cases (lots of 
users, though with relatively few active connections). It runs a bog 
standard Samba3 + winbind member server (NT or ADS) as far as I can tell.

Having said that, the 2 shortcomings I have found are with windows 7 
clients...  troubles doing offline files (there are  bunch of tweaks, 
but none work perfectly) and it doesnt work too well with the libraries 
feature in win7 (it needs indexing o some sort that isn't povided by 
samba I think)

BTW, would a Samba4 member server setup help with these issues? If it 
did, I'd upgrade even if it did invaidate warranty...
