Speex dev - Oct 2010 - Acoustic Echo Canceller Implementation

Hello!
I'm working in an audio and video laboratory that is developing a
video-conference software. We are in trouble with Echo Acoustic.
So I found speex and it's supposed to be implemented the canceller there.
But I didn't find it helpful for windows - our software will run in Vista or
XP.

Do you have an Acoustic Echo Canceller implemented to windows?
If not, do you know another tool or codec that can help me with that?

Obs: It's an Universitarian Project - Federal University of Rio Grande do
Sul - Brazil.

Thanks for your atention.
