Thanks for the feedback.  I'll open a form posting.  As for the echo - 
no joy in the _submit or _validate functions (I think it has to do with 
included files being processed then an ob_clear() being called).  the 
watchdog function sounds promising, I'll look into it.

The likely culprit is my code, not the form api per se.  But I'm 
struggling trying to figure out why my code is not raising errors, but 
not working.

Anyways, thanks again, I'll move this to the forums.
