Hi,

I am thinking of middleboxes that expect "text-only" protocols and we  
would introduce binary data in the payload. That's not going to go  
down well, but in the end it's just another failure mode.

I guess whichever way we go, we really need to think carefully about  
failure modes.

Let me add one more bullet to the list, after my discussion with  
Murari today.
Payload
- involves mixing the control and data plane in host stacks; will be  
much more difficult to implement
