True. But Tor is the large anonymity network that we have. I2P is cool, but it's too small. For high latency, perhaps Mixmaster remailers via alt.anonymous.messages is still workable. Last I checked, there was a Tor onion news server.

I agree about unworkability for real-time communication. But there, you want to keep messages small. And use padding. Trying to make live streaming anonymous is nontrivial.
