Dear Authors,
I've read the draft and would appreciate your clarification to my question:

   - What benefits do you see in defining two new ACH types for STAMP
   protocol over a PW?

I believe that there are no apparent advantages of using PW, i.e., without
IP/UDP headers, encapsulation compared to using IP/UDP. The latter can be
easily done using ACH types 0x0021 and 0x0057 for IPv4 and IPv6 address
family respectively.

What do you think?

Regards,
Greg
