[Opensim-dev] User/Agent/Avatar (again) and multiple logins

[Diva Canto]

Hi,

I've been noticing that there is a certain confusion in the code about 
the names of methods and fields when it comes to denoting a user vs. an 
agent vs. an avatar. That could be cleaned up, eventually, if someone is 
up for a little bit of renaming. But there seems to be a deeper 
confusion in the data structures themselves, and that's much nastier to 
deal with. Specifically, agents take the UUIDs of the users they 
represent, instead of having a UUID of their own and pointing to the 
user. By doing this, the separation between user and agent is defeated. 
Also, AgentCircuitData takes a copy of the first and last names of the 
users they represent, and this is a bit fragile when one wants to 
process the names of users in interesting ways.

I really like the conceptual separation of those 3 things. I can imagine 
situations where it is advantageous for a single user to be logged in 
several times -- e.g. wanting to attend multiple events at the same time.

Is this "id collapse" being done for optimization? Or is this one of 
those things that made it to the code and never got challenged? Or is 
this a well-known TODO?

This is not urgent, I'm just wondering what the story is.
