No globals, sorry. You can make a variable static in some of your
classes, but it is discouraged in general (e.g. you would not be able to
use O.switchWorld() consistently). You have to update that number
somehow, anyways.
 
If you need that number just once in a while, count the interactions
like this:

long n=0;
FOREACH(const shared_ptr<Interaction>& I, *rootBody->interaction){ if(I->isReal()) n++; }

In python, you can use O.interactions.countReal().
