Stef, Dolphin's solution is to use proxies. Rather than serializing the class itself, one might prefer to serialize a proxy that knows enough to find the appropriate object once it "wakes up" in the new image. In the case of a class, it should be enough to know the name, so the proxy would have that one aspect and it would resolve itself by looking for it in the system dictionary. There is a little more to it, but that is the basic idea.

I need to save a class (not the instances) in a binary format and I was wondering if somebody got experience with that.
