Interesting idea, but isn't ssh very sluggish when it comes to throughput and latency? Doesn't it cost quite a bit more in CPU? I'd hate to make ssh the protocol replacement for http for a busy site.

It depends on the clipher you're using and the implementation/hardware.

It depends more on the TCP window size; OpenSSH uses a small one by default and it cannot be changed.
