Except that symbol creation isn't the issue. By definition, each time a symbol is "created" you are getting a new unique symbol. Frames/contexts/realms have nothing to to with that. The issue, is providing access to an already created symbol across such boundaries. As I have pointed out in other messages, this isn't a problem that it unique to symbols. It is isomorphic with use cases for sharing any kind of object across such boundaries.
