1. Yes, just keep in mind to free any temporary data, and that garray2
will have to be freed by whatever needs the copy.

2. You can add anything as data (answers 3 also) data is just a pointer
to the "actual data". to clarify.. no you cannot add an "int". but you
can add a pointer to an int* or &int, string, GList, etc.

3. yes.. just add a pointer to your structure as ->data and typecast
where needed.
