Thank you! There are indeed lots of choices, which makes things interesting. How to balance/optimize the internal and external brain fragments could be an interesting problem and may even be the basis of another generation of culture wars.
Once the consciousness is externalized, then so long as the API and real-time constraints are consistent, you could have multiple physical bodies. You want to go for a drive? Be the person, then become the car. Eliminates any need for mechanical controls (unreliable) and turns the fully networked car into something useful.
It would be interesting to fully explore the impact on the mind. Sorry, Matrix and Neuromancer - excellent fiction though they were - really didn't scratch the surface. However, to say my writing varies is like saying gravity isn't uniform. I can usually manage a decent-sized chapter before fading, but I would need help getting out either a book on the general theory of mind or a story based on such a concept.
P.S. This box contains infinite commas. Be warned, they are freshly baked and may stick to each other.
