This looks really cool - eHomeUpgrade has a sneak preview of OneVoice Technologies' new Media Center Communicator, complete with voice navigation of Media Center, an Email client, SMS Text support, VOIP, video chat and more.

I haven't tried their application yet but I'm interested to do so.  In fact, if any of you are working specifically on Media Center applications and are interested in meeting up at CES, please let me know- drop and email with basic details and I'll do my best to try to set up a meeting with our team.
