Heh The twist of fate that JustinCC was talking about is that there's a Replace of UUID to Guid(or the other way? I forgot!) in the current serialization before it hits the deserializer. This 'hack' was added by me a long time ago when the types were changed in order to update LibOMV and still have all old inventory stored before that version work after the libomv update. It's been so long that I forgot about it :P. I turns out that old versions can still read the new UUID automagically based on a twist of fate :P.
I vote for removing that hack now.. since it's no longer needed.
