i would like to be able to transfer a droplet as is (completely with IP address and RUNNING) from an account to another. this has nothing to do with droplet properties and it should be a simple change in database (for droplet_id change owner_id from user_X to user_Y or something like this).
from the interface point of view, it can be handled in a similar way with snapshot transfer, with one user offering and another user accepting the transfer
this is useful for billing purposes.
