It IS a cool thought...though if I die, I'd probably just follow you guys around as an intangible, immortal spirit, capable of possession (and still communicating with my cat).
And if Neo TOUCHED me, I'd use my spirit form to harm any other spirits he took in, exhausting them to the point they couldn't be used by him.
