The solution to the ventrilo issue is called ventriloctrl and can be found at http://ubuntuforums.org/showpost.php?p=2662867&postcount=83 . Getting push-to-talk working is not really the hurdle here, the problem is that when the Wow window has focus, there's no way for Vent to know you hit the key, which is how most people would be using vent+Wow. The post is outdated but the README that comes with the zip file explains what to do.
