For some reason i`had stopped at summer of 2010 my project of IVAO client.
I thinked, that IVAO finished they library, but...
There is http://www.flightgear.ru/forum/download/file.php?id=628
my alpha project of proxy beetwen IVAO and FG.
It`s changed source of squawkgear
1) Install Python
2) Copy startx.bat to Flightgear\bin\Win32 ( it`s run command for FG)
3) Copy menubar.xml to Flightgear\data\gui\
Copy sq_*.xml to Flightgear\data\gui\dialogs
Copy squawk.xml to Flightgear\data\protocol
4) Run proxy - python.exe squawkgear
5) Run FG via script startx.bat
(FG automatically connect to proxy, in FG appear new menu, there is you can change Login, Pass, Flight Plan. Changing of type aircraft in Flight Plan - you change you view for others pilots (seeng ICAO base of naming aircrafts)
Changing some strings in file mp.py - you change view of pilots aircrafts in your FG.
There is not done Chatting, Voice and some other functions. If you can done this is forgotten project - big thanks.
In theory it`is also working in Vatsim, if change IP of servers in setup.
For voice client may be used http://xp2ts.sourceforge.net/
It`s save your coordinate and tuned freq to local file.
Python script parsed whazzup file from server and local file for connecting to needed server
