Body Surf: Pretty much anyone can do this – even the pure biosapiences with the aid of some Very Large brain scanning technology – but since they can mostly only enter bodies they have brain ackles for, which mostly means “owned or rented”, reinstantiation isn’t the sort of problem that the more possession-type body surfers are.  And it’s also quite useful when you consider, well, how you don’t want to take your fragile meatbody with you when working construction on a framework hanging a couple of hundred miles over the solar photosphere, and you really don’t want to take your construction ‘shell home to the family.  Or, of course, when one of your bodies finds a way to get dead.
