Well, the post-show is never archived, so that probably won't happen. I will try to get a back-up of some of it though before it vanishes from the justin.tv archive. You can register an account on there and create clips of things from recent episodes:

They only keep stuff archived for about 72 hours or so... before you no longer have a chance to make clips/download the stuff.
