I wouldn't use any scanning technique to upload, since IMO the copy wouldn't be "me"; I'd rather have gradual uploading by means of computer implants, or perhaps nano-assisted neuron-by-neuron replacement of the biomass by artificial structures _while I'm conscious_ (yeah,yeah, call me old-fashioned... ;-)

Well, in my favourite scenario that cyborg would be *me* (no copies), possibly just a "brain in a jar" hooked up via direct neural interfaces to a massive computer and support systems (with "weak" AI "agents" to assist my thinking etc.). This contraption, thanks to the power of nano soon many miles accross, would float in space (a sphere would probably be the most logical design). "I" would live in VR worlds or interact directly with the outside world trough probes and perhaps various larger (humanoid?) avatars.

The biological self, soon only a insignificant little piece of the megabrain, could be removed as soon as all its data had been copied, and my "mind" had migrated into the rest of the structure. Then it would be comparable to removing a single, obsolete brain cell.
