[JDEV] How to get Foward List from MSN_Transport

[stl]

Hi, everyone:

Always only use jabber and never pay attention to its implement, but now I need show the friends' list automatically in my jabber client, so I tried to get this function. 
After read the source code of msn transport I found I still couldn't understand its structure clearly, maybe I should read jabber's source code first.
So I want to ask:
1.Does jabber msn transport already has this function, or does anyone has already done that?
2.Where I can get any document or web sites describing msn transport a little detailed?
3.Any flowchart abou the process how jabber client connects with jabber msn transport? (I read the Mike Mintz's articles about MSN protocol so I guess I can understand how msn transport communicates with a msn server)
4.About msn transport:
  a.I guess ns.c will deal with those askings from client to jabber server, the jabber server will use functions in cmd.c to send asking to msn server, is it true?
  b.The only place I can find LST command is in sync.c, function mt_user_syn, but I can't understand what function mt_user_sync_final and mt_user_sync_walk are doing.
  c.What the functions in iq.c doing?
Many questions, :-)  and thanks in advance.
