Perhaps add Mark Allman with you to the reviewers (in the writeup), since his review in the 
WG was so significant?

I'm sure this is a beautiful algorithm.
But after reading the RFC, I still have no knowledge on whether or not I should be interested in adding this to my TCP implementation.
- Always?
- Only when I am in an environment where non-congestion loss is common?
- Only if I like having more code in my TCP?
- Other criteria?
This is not worth braking the progress of the document for. But I miss it.

In Section 2., the draft says:

   If the Eifel response algorithm is implemented at the TCP sender, it
   MUST be implemented together with a detection algorithm that is
   specified in an RFC.

Is there any expectation of specific RFC categories?

  In the security considerations, we learn that the Eifel
  response algorithm SHOULD only be run together with detection
  algorithms that are known to be safe against such "ACK spoofing
  attacks."  Are there other characteristics of detection algorithms
  that ought to be considered?  I would like to see the section 1
  list the characteristics of an "appropriate detection algorithm."

What does this step do, in terms of what _this_ spec needs to know?
Does it produce a results that says "spurius retransmit detected,
execute step 7"? (that is kind of what I would think, since the
response would presumbaly only be executed when needed...) It would be
good to make this more clear.
