Hi David

indeed, I fully agree, the calib blob holds no privacy relevant info. 
once the vote concludes positive I have the mandat to talk with the ODM. 
the idea is to provide a http/rest endpoint for the ODM to

a) grab a blob with the serial number and other TBD data to be place 
inside the flash

b) upload the calibration data for backup storage,
