WOW! Faster than iTALC and pretty easy to install as well. I'll be letting you know how this continues--Now to translate some button names--or alkisg would you do them since I can't copy paste them into a translator? I'll make it a neat write up though and put it into the wiki when I've tested it a bit more. This is cool :)
