A scope is a short.

When discussing scopes, this was seen as sufficient, but if you want 
bloom filters this won't suffice...

The question is can you do with roughly 32'000 scopes per member ? If 
this is the case, you could maintain a hashmap of scope-ids and bloom 
filters (for example)...

If not, we need to revisit this. If you need a different type, let's 
discuss this, but it should be a type that can be used as a key into a 
hashmap...
