Sorry you couldn't make it.  It was a very good meeting overall, IMO.

This was discussed at one point during the policy discussion in Kigali, 
FWIW.  Others may remember better than I do the specifics of that 
discussion, but...

I don't think the entire /8 would be tied up and unusable.  As best I 
can tell, this policy, if implemented as written, will have the result 
of rationing medium and large ISPs from continuing to acquire new IPv4 
space for assignment to their customers after they've received four 
/23s, which in turn will encourage those ISPs' larger customers to go to 
AfriNIC directly to get space under end user policies.  This will result 
in more organizations interacting with AfriNIC directly, and less 
aggregation within the last /8 than would occur without this policy.

I have no comment at this point as to whether that is a better or worse 
overall outcome than other alternatives...
