	Ah, I guess I wasn't clear.
	As of right now, there's no way to specify the host ID. ColdSync
just uses the host's IPv4 address. When it becomes possible to set the
host ID, it should still default to the IPv4 address. So if you don't set
up a config file, the host ID will be the IPv4 address.
	However, if you want to set the host ID manually, then you'll have
to manually update your config file. Though it should be possible to
specify well-defined abbreviations, e.g. "hostid: hostid;" should set the
host ID to the value returned by gethostid(2).

	True. (It's _not_ acceptable to require the user to re-register
the OS after installing a new NIC, but that's a different rant :-) ).
	Of course, a slow sync is always safe, albeit slow. I'm more
concerned with "unsafe" operations, i.e. ones that might delete data that
shouldn't be deleted.
