I guess thats the reason. You will still be able to pass a struct as change 
but you need to serialize all pointers of this struct. But the structs of the 
the opie-sync plugin are very heavy to serialize. The contact_data (in 
opie_comms.h) for example have more then 40 pointers which have to be 
serialized.

You have to write marshall and demarshall functions for each object type and 
register them with:

(Example from formats/file.c in trunk of libopensync):
        osync_env_format_set_marshall_func(env, "file", marshall_file);
        osync_env_format_set_demarshall_func(env, "file", demarshall_file);

The de/marshall functions of the formats/file.c are maybe a good reference how 
this is working. But the file struct only have one pointer not 40 ;)

(For further questions/discusson we should maybe move this to opensync-devel)
