[IDD #SAX-259155]: GEM feed request

Hi John, 

Hard to say, they respond quickly, but this matter may need some vetting from 
"powers that be". I am in comm's with CMC EC today, so maybe we'll here back 
soon. If not too much trouble you may want to script some pulls for the 
interim. I will keep you in the loop and pass information on to you as soon as 
I hear anything back.

Cheers,

Jeff
