Honestly, what is the demand of it in terms of devices, networks right 
now and for the next few years ?
Taking aggregation out of the equation, what would be the issue of using 
IP space allocated by the RIRs to space agencies with supposedly pretty 
low demand.

Yes I do. It is well established and can accommodate as necessary. It 
has the basis to adapt to whatever necessary and acquire the necessary 
technical competence. Furthermore RIRs represent the interest of each 
regional internet community worldwide.

Really don't understand by some wish to bypass the RIR system and create 
something new and unknown for something that doesn't have justified demand.
