MIB600, yes. What is interesting though, is that with SF & the modifs  
below, Deluge T2 works correctly.
I can inject, reprogram, ping

As for disseminate or disseminate & reprogram, the message gets sent  
to the mote, it flashes green at some point, but nothing gets done  
besides this.

I guess it's not related to me using this modif on an MIB600.

Is these something usually preventing the dissemination from working ?

Slashdot comment about Dr Bussard getting navy funding for his nuclear  
fusion device following his speech at Google:
"Cue all the jokes about the reactor having an "I feel lucky" button,  
but with a "Do you feel lucky, punk?" Navy twist to them."
