hi,

the usual way is doing just that -- sending to a symbol -- on the gui side, while binding your external object to this symbol on the pd side. Since that symbol should be somehow unique, a good way would be to perform some name mangling with an object's address, e.g. using "%x" pattern in sprintf. You will find many such examples in Miller's (and other's) code.
