I have been following the falcor announcements, presentations and discussions for a few months. I am really impressed at what a good job the Netflix team has done with introducing the json graph concepts, I've learned a lot it regardless of falcor. Kudos Netflix!

I really like the concepts and client/server model. If it is performant, it will be fun to see persistent videogame worlds written through falcor. To that end, would it be possible/effective to hang parts of the graph off of WeakMap so that big, not recently used parts of the graph are allowed to fall away? (Perhaps that is how it works right now, I haven't had a chance to look at the source code, pardon my ignorance...)
