How complicated are the objects you want to transmit? If they're just
strings, integers, floats, and lists or dictionaries of the above,
then you could use JSON instead; that's much safer, but (and because)
it's majorly restricted. Sometimes it's worth warping your data
structure slightly (eg use a dict and global functions instead of a
custom object with methods) to improve security.
