In my opinion, namescase sensitivity is protocol specific.  Another
instance
of this other than host name is username.  Username in Windows is case
insensitive while on unix is case sensitive.

It seems to me the simple solution is to keep the original name the
admin
typed in in the database and let the protocol pick which name they want
to use?

Hm, OK, I didn't get this the first time I read it, apologies.
Assuming that I get it now, however ~:^)  But what it sounds like is
that we would have case-sticky but case-insensitive names?  I can
get behind this idea, because it satisfies pretty much all reasonable
needs. It allows us to "help" the customer not do something dim while
still allowing them to use case to their own naming style.  I don't
think anyone really wants two different host, volume or interface names
that differ only in case, but I'm sure they would want to be able to
name a volume "CountDracula" and not see "COUNTDRACULA" </shiver> or
"countdracula" in the NFS exports.  Or in any UI output. CIFS users are
so used to be being case-abused I'm sure they don't care ~:^)
