Thanks. I haven't looked at them yet, but was thinking along the lines
of separate shared segments per share. However, that becomes expensive
if the customer wants thousands of shares (and I have heard of that,
although most of them seem to be fake shares of the sort you get when
you dynamically create a share per user for their home directory, for
example.)
