[Samba] Hide share with a twist

[Ashley M. Kirchner]

    I'm setting up a single SAMBA server that will have different 
netbioses names:

    netbios aliases SAMBASRV BACKUPSRV

    Then I have two shares defined, [assets] and [digital], different 
path on both.

    Now, when I connect to \\SAMBASRV from my windows machine, I see 
both the 'assets' and 'digital' shares available.  Same if I connect to 
\\BACKUPSRV.  Is there a way to hide a share based on what netbios name 
the user connected with?  For example, if a user connects with 
\\SAMBASRV I only want them to be able to see the 'assets' share, and if 
one connects with the \\BACKUPSRV name, they should only see the 
'digital' share.  All users connect as guests, no passwords involved or 
anything like that.  It's all shared.
