Callback function from Forms to server?

First of all thanks to Thomas Kyte for the answer to my last question (about stored procedures acting like cursors). It seems the post did'nt make it to the newsgroup.

What would be the recommended way to implement a callback function in Forms 4.5. The scenario would be as follows: Forms activates a server stored procedure, and somehow passes a reference to a procedure in a Forms package. The server procedure would call the passed procedure to communicate asincronically with Forms. This could be used to implement progress indicators, for example, and is generally useful when the procedure has an undefined run length. For example, a server procedure that reads a hardware device and sends succesive messages to Forms.

Again, thanks for any suggestions.
