Sounds good, have been using Syphon with Quartz Composer for this and unfortunately can't get Camtwist to work at the moment, but would be interested to see how they compare.
I didn't use Quartz Composer + Syphon. The advantage with Camtwist it is that you can choose what application to printscreen and you can show or not mouse point in your output video
