Once we start referring to National laws, we will make it complex again. 
IMHO ... the allowance of 5 IPs per user more than compensates for the 
0.5 multiplier for part-time students. In most institutions, campus 
access for full/partime students are spaced by time of the day or 
academic season.  The closer we are to a scenario that works across 
Africa without hostmasters iterating and asking for more documentations 
that could be hard for people to get, the better we are.

Lets keep the math and definitions very simple.
