* e.g.
```
struct BaseIp { ptr: BasePtr }
struct Tx { b: BaseIP }
impl BaseIp { fn tx(&mut self) -> Tx { Tx { self } }
```
I guess I sort of need a ref count like shared object in this case? Rc\<> or Arc\<> or whatever, but that also seems kind of insane... in the end its a pointer to the address of the IP block I'm sharing
