It depends upon how your world sees objects. If it sees objects as a
bit of data that's interpreted by C++ code then transferring is
trivial.

However, if it sees objects as data and script code (perhaps
specific to the object), and C++ code to run the script code, then
transferring objects is tricky because the script code moves from
one system to another, and could act like a virus, worm, or anything
else it wants to. Limits could be put on the scripts, but then
objects can't do as much. Script code is used because it allows for
MUCH more flexibility in world design than just seeing objects as
data.
