I think free numbers are best

Yes. This could be enforced either by not allowing the person to go 
further with the total of 100, or by adjusting them proportioannly to a 
total to 100.

See above.

34, 33, 33.

That could be useful, as it is often requested from users.


Additional point:
say affiliation A is Dept X, School Y, University Z
B is School Y, University Z
C is Think Tank W

then it must always be that B>=A, and B+C=100. The reason is that A is 
part of B.
