Sorry, but this strikes me as a hack. I'd much rather
a) Fix the config file to allow you to set the host ID in the
config file. This should solve the problem of DHCP clients with
transient IP addresses.
b) Have one or more ancillary files that give the ID of the
host with which a given database was synced. That way, this
information can be rdisted along with the databases, and ColdSync can
make a more informed decision as to whether or not to do a slow sync.
