Ok, if I have 2 IP addresses in each packet, I could use 2 different 
etts to keep their subtrees separated.

But if I have N IP addresses, with N different from packet to packet, 
how can (or should) I implement etts and subtrees logic?

Probably, if N is limited, I can register Nmax etts in advance.

This is not important. If the user navigates across packets, he could 
find these subtrees always closed.

If I register a common set of etts, the state of the subtrees will be 
kept from packet to packet, for subtrees present in both. Am I right? 
This seems the right way.

Thanks.
