I hope I am not stating the obvious here, but you can get yourself a
pseudo-GUID if you ask the user for a string that identifies the installation
(e.g. my-dev, my-staging, my-production) and use that and the object internal
id to create a GUID (no hashing necessary).
When you import objects INTO an installation you keep a table that maps the
remote object GUID to the local object GUID. Then you have a well defined one
to one mapping, and you are able to update the object again, reference to it
(this comment is for that node), or even send it back if needed. You can also
keep track of which object came from where if you ever need this kind of
I don't trust arbitrary strings like domain, IP, MAC etc as they have the
tendency to change. Asking the user for a unique id (and it only has to be
unique in his world) should be good enough here.
