I have made a little mxj-object, that you can include in your max patcher to get you Google talking from Max/Msp right away.
It works for me - Use it at your own risk :-)
Download and extract MaxGoogleTalk.zip to somewhere on your harddrive.
Find and edit C:\Program Files\Cycling '74\Max 5.0\Cycling '74\java\max.java.config.txt
Add these lines
Remember to restart Max for it to take effect
