 From what you're saying, there aren't many differences between your  
perception of 4.3 and what is in 5.0;
The reason why I'm calling this working version 5.0 has objective  
grounds, related to the changes in the DB schema; moving to this new  
version is a bit beyond a simple migration script; so keeping the  
planetlab4 db intact and using it to populate planetlab5 sounds like  
the right thing to do.

There indeed is a lot to discuss; I will bring the major design  
decisions to devel.
At this stage I've just done a plain renaming of NodeNetwork into  
Interface; the rationale being that links between nodes are known as  
Nlinks and links between interfaces are known as Ilinks. I have not  
looked into Mary's UML designs yet.
