The standard approach I've seen used:
1) While objects are within each other's direct working sets the
exchange updates as state changes occur (this is part of the
standard notify message semantics).
2) Periodically exchange checksum's of their current states and
use that to ensure correctness (update only as needed). This
prevents slippage (and should be logged as a form of error
detection) as well as communication corruption (simple line noise,
local computation/prediction error, man in the middle, whatever).
3) When objects are not members of the other's direct working set,
stop sending state change messages.
