Gotta look at this.

Xou can even add indicators like in 

... values (:id,:name_first, :name_middle:nm_ind, :name_last, ...

If nm_ind is set to -1 the name_middle entry will be set to NULL.

It is. In fact I already submitted a patch for the PREPARE and EXECUTE
commands. James, if you'd like to test this I can send you the source until
it makes its way into CVS.
