From everything else you said, I think I'm decided that changing the actual 
hostname is a Bad Idea.  The question is just then where to store the 
hostname so that other software could use it.

One option is to store it under

  CCS\Services\sanbootconf\Parameters\iBFT\NIC\0\hostname

i.e. store all of the parameters from the iBFT (or sBFT, or whatever firmware 
boot table we're using) in registry entries corresponding to the table 
structure.  This has the advantage that it exposes all of the firmware boot 
table information, without requiring a user to parse the raw table.  The 
disadvantage is that the user needs to be specifically aware of sanbootconf.

Another option is to find a suitable generic registry entry to hold the 
DHCP-assigned hostname.  This would have the advantage that the user does not 
need to be specifically aware of sanbootconf.  Unfortunately, I don't know of 
any such registry entry.
