I just published a Hands-Free texting app called Shout. Just say a phrase like "Text Doug With I am On My Way Home" and Shout will search your contacts for matches, confirm "Sending 'I am on my way home' to 'Doug Hansknecht', correct?". Simply tap the Big Green Yes button and you're done. There's a video demo here: YouTube - Shout - One Tap Texting Demo. Sorry about the video quality! Let me know what you think.
