What implementations are you referring to? Does libdbus have any such
assumptions? I have this line in one of my method call handlers:

    dbus_message_iter_get_fixed_array(&array_iter, &data, &data_length);

and I expect that to handle byte arrays of size 67108864 (i.e. the
maximum array size according to the D-Bus spec).
